|
|
The package contains semantic conventions from the `v1.16.0` version of the OpenTelemetry specification. (#3579)
|
|
- Metric instruments to `go.opentelemetry.io/otel/metric/instrument`.
|
|
These instruments are use as replacements of the deprecated `go.opentelemetry.io/otel/metric/instrument/{asyncfloat64,asyncint64,syncfloat64,syncint64}` packages.(#3575, #3586)

|
This type is used to represent min/max values and still be able to distinguish unset and zero values. (#3487)
|
|
- The `go.opentelemetry.io/otel/semconv/v1.17.0` package.
|
|

|
|
### Changed
|
|
|
|
- Jaeger and Zipkin exporter use `github.com/go-logr/logr` as the logging interface, and add the `WithLogr` option. (#3497, #3500)
|
|
- Instrument configuration in `go.opentelemetry.io/otel/metric/instrument` is split into specific options and configuration based on the instrument type. (#3507)
|
|
- Use the added `Int64Option` type to configure instruments from `go.opentelemetry.io/otel/metric/instrument/syncint64`.
|
|
- Use the added `Float64Option` type to configure instruments from `go.opentelemetry.io/otel/metric/instrument/syncfloat64`.
|
|
- Use the added `Int64ObserverOption` type to configure instruments from `go.opentelemetry.io/otel/metric/instrument/asyncint64`.
|
|
- Use the added `Float64ObserverOption` type to configure instruments from `go.opentelemetry.io/otel/metric/instrument/asyncfloat64`.
|
|
- Return a `Registration` from the `RegisterCallback` method of a `Meter` in the `go.opentelemetry.io/otel/metric` package.
|
|
This `Registration` can be used to unregister callbacks. (#3522)
|
|
- Global error handler uses an atomic value instead of a mutex. (#3543)
|
|
- Add `NewMetricProducer` to `go.opentelemetry.io/otel/bridge/opencensus`, which can be used to pass OpenCensus metrics to an OpenTelemetry Reader. (#3541)
|
|
- Global logger uses an atomic value instead of a mutex. (#3545)
|
|
- The `Shutdown` method of the `"go.opentelemetry.io/otel/sdk/trace".TracerProvider` releases all computational resources when called the first time. (#3551)
|
|
- The `Sampler` returned from `TraceIDRatioBased` `go.opentelemetry.io/otel/sdk/trace` now uses the rightmost bits for sampling decisions.
|
|
This fixes random sampling when using ID generators like `xray.IDGenerator` and increasing parity with other language implementations. (#3557)
|
|
- Errors from `go.opentelemetry.io/otel/exporters/otlp/otlptrace` exporters are wrapped in errors identifying their signal name.
|
|
Existing users of the exporters attempting to identify specific errors will need to use `errors.Unwrap()` to get the underlying error. (#3516)
|
|
- Exporters from `go.opentelemetry.io/otel/exporters/otlp` will print the final retryable error message when attempts to retry time out. (#3514)
|
|
- The instrument kind names in `go.opentelemetry.io/otel/sdk/metric` are updated to match the API. (#3562)
|
|
- `InstrumentKindSyncCounter` is renamed to `InstrumentKindCounter`
|
|
- `InstrumentKindSyncUpDownCounter` is renamed to `InstrumentKindUpDownCounter`
|
|
- `InstrumentKindSyncHistogram` is renamed to `InstrumentKindHistogram`
|
|
- `InstrumentKindAsyncCounter` is renamed to `InstrumentKindObservableCounter`
|
|
- `InstrumentKindAsyncUpDownCounter` is renamed to `InstrumentKindObservableUpDownCounter`
|
|
- `InstrumentKindAsyncGauge` is renamed to `InstrumentKindObservableGauge`
|
|
- The `RegisterCallback` method of the `Meter` in `go.opentelemetry.io/otel/metric` changed.
|
|
- The named `Callback` replaces the inline function parameter. (#3564)
|
|
- `Callback` is required to return an error. (#3576)
|
|
- `Callback` accepts the added `Observer` parameter added.
|
|
This new parameter is used by `Callback` implementations to observe values for asynchronous instruments instead of calling the `Observe` method of the instrument directly. (#3584)
|
|
- The slice of `instrument.Asynchronous` is now passed as a variadic argument. (#3587)
|
|
- The exporter from `go.opentelemetry.io/otel/exporters/zipkin` is updated to use the `v1.16.0` version of semantic conventions.
|
|
This means it no longer uses the removed `net.peer.ip` or `http.host` attributes to determine the remote endpoint.
|
|
Instead it uses the `net.sock.peer` attributes. (#3581)
|
|
- The `Min` and `Max` fields of the `HistogramDataPoint` in `go.opentelemetry.io/otel/sdk/metric/metricdata` are now defined with the added `Extrema` type instead of a `*float64`. (#3487)
|
|
|
|
### Fixed
|
|
|
|
- Asynchronous instruments that use sum aggregators and attribute filters correctly add values from equivalent attribute sets that have been filtered. (#3439, #3549)
|
|
- The `RegisterCallback` method of the `Meter` from `go.opentelemetry.io/otel/sdk/metric` only registers a callback for instruments created by that meter.
|
|
Trying to register a callback with instruments from a different meter will result in an error being returned. (#3584)
|
|
|
|
### Deprecated
|
|
|
|
- The `NewMetricExporter` in `go.opentelemetry.io/otel/bridge/opencensus` is deprecated.

## [1.11.2/0.34.0] 2022-12-05
|
|
|
|
### Added
|
|
|
|
- The `WithView` `Option` is added to the `go.opentelemetry.io/otel/sdk/metric` package.
|
|
This option is used to configure the view(s) a `MeterProvider` will use for all `Reader`s that are registered with it. (#3387)
|
|
- Add Instrumentation Scope and Version as info metric and label in Prometheus exporter.
|
|
This can be disabled using the `WithoutScopeInfo()` option added to that package.(#3273, #3357)
|
|
- OTLP exporters now recognize: (#3363)
|
|
- `OTEL_EXPORTER_OTLP_INSECURE`
|
|
- `OTEL_EXPORTER_OTLP_TRACES_INSECURE`
|
|
- `OTEL_EXPORTER_OTLP_METRICS_INSECURE`

|
|
- `OTEL_EXPORTER_OTLP_TRACES_CLIENT_CERTIFICATE`
|
|
- `OTEL_EXPORTER_OTLP_METRICS_CLIENT_CERTIFICATE`
|
|
- The `View` type and related `NewView` function to create a view according to the OpenTelemetry specification are added to `go.opentelemetry.io/otel/sdk/metric`.
|
|
These additions are replacements for the `View` type and `New` function from `go.opentelemetry.io/otel/sdk/metric/view`. (#3459)
|
|
- The `Instrument` and `InstrumentKind` type are added to `go.opentelemetry.io/otel/sdk/metric`.
|
|
These additions are replacements for the `Instrument` and `InstrumentKind` types from `go.opentelemetry.io/otel/sdk/metric/view`. (#3459)
|
|
- The `Stream` type is added to `go.opentelemetry.io/otel/sdk/metric` to define a metric data stream a view will produce. (#3459)
|
|
- The `AssertHasAttributes` allows instrument authors to test that datapoints returned have appropriate attributes. (#3487)
|
|
|
|
### Changed
|
|
|
|
- The `"go.opentelemetry.io/otel/sdk/metric".WithReader` option no longer accepts views to associate with the `Reader`.
|
|
Instead, views are now registered directly with the `MeterProvider` via the new `WithView` option.
|
|
The views registered with the `MeterProvider` apply to all `Reader`s. (#3387)
|
|
- The `Temporality(view.InstrumentKind) metricdata.Temporality` and `Aggregation(view.InstrumentKind) aggregation.Aggregation` methods are added to the `"go.opentelemetry.io/otel/sdk/metric".Exporter` interface. (#3260)
|
|
- The `Temporality(view.InstrumentKind) metricdata.Temporality` and `Aggregation(view.InstrumentKind) aggregation.Aggregation` methods are added to the `"go.opentelemetry.io/otel/exporters/otlp/otlpmetric".Client` interface. (#3260)
|
|
- The `WithTemporalitySelector` and `WithAggregationSelector` `ReaderOption`s have been changed to `ManualReaderOption`s in the `go.opentelemetry.io/otel/sdk/metric` package. (#3260)
|
|
- The periodic reader in the `go.opentelemetry.io/otel/sdk/metric` package now uses the temporality and aggregation selectors from its configured exporter instead of accepting them as options. (#3260)
|
|
|
|
### Fixed
|
|
|
|
- The `go.opentelemetry.io/otel/exporters/prometheus` exporter fixes duplicated `_total` suffixes. (#3369)
|
|
- Remove comparable requirement for `Reader`s. (#3387)
|
|
- Cumulative metrics from the OpenCensus bridge (`go.opentelemetry.io/otel/bridge/opencensus`) are defined as monotonic sums, instead of non-monotonic. (#3389)
|
|
- Asynchronous counters (`Counter` and `UpDownCounter`) from the metric SDK now produce delta sums when configured with delta temporality. (#3398)
|
|
- Exported `Status` codes in the `go.opentelemetry.io/otel/exporters/zipkin` exporter are now exported as all upper case values. (#3340)

|
- `Aggregation`s from `go.opentelemetry.io/otel/sdk/metric` with no data are not exported. (#3394, #3436)
|
|
- Re-enabled Attribute Filters in the Metric SDK. (#3396)
|
|
- Asynchronous callbacks are only called if they are registered with at least one instrument that does not use drop aggragation. (#3408)
|
|
- Do not report empty partial-success responses in the `go.opentelemetry.io/otel/exporters/otlp` exporters. (#3438, #3432)
|
|
- Handle partial success responses in `go.opentelemetry.io/otel/exporters/otlp/otlpmetric` exporters. (#3162, #3440)
|
|
- Prevent duplicate Prometheus description, unit, and type. (#3469)
|
|
- Prevents panic when using incorrect `attribute.Value.As[Type]Slice()`. (#3489)

|
|
|
|
- The `go.opentelemetry.io/otel/exporters/otlp/otlpmetric.Client` interface is removed. (#3486)
|
|
- The `go.opentelemetry.io/otel/exporters/otlp/otlpmetric.New` function is removed. Use the `otlpmetric[http|grpc].New` directly. (#3486)
|
|
|
|
### Deprecated
|
|
|
|
- The `go.opentelemetry.io/otel/sdk/metric/view` package is deprecated.
|

|
|
|
|
## [1.11.1/0.33.0] 2022-10-19
|
|
|
|
### Added
|
|
|
|
- The Prometheus exporter in `go.opentelemetry.io/otel/exporters/prometheus` registers with a Prometheus registerer on creation.
|
|
By default, it will register with the default Prometheus registerer.
|
|
A non-default registerer can be used by passing the `WithRegisterer` option. (#3239)
|
|
- Added the `WithAggregationSelector` option to the `go.opentelemetry.io/otel/exporters/prometheus` package to change the default `AggregationSelector` used. (#3341)
|
|
- The Prometheus exporter in `go.opentelemetry.io/otel/exporters/prometheus` converts the `Resource` associated with metric exports into a `target_info` metric. (#3285)
|
|
|
|
### Changed
|
|
|
|
- The `"go.opentelemetry.io/otel/exporters/prometheus".New` function is updated to return an error.
|
|
It will return an error if the exporter fails to register with Prometheus. (#3239)
|
|
|
|
### Fixed
|
|
|
|
- The URL-encoded values from the `OTEL_RESOURCE_ATTRIBUTES` environment variable are decoded. (#2963)
|
|
- The `baggage.NewMember` function decodes the `value` parameter instead of directly using it.
|
|
This fixes the implementation to be compliant with the W3C specification. (#3226)
|
|
- Slice attributes of the `attribute` package are now comparable based on their value, not instance. (#3108 #3252)
|
|
- The `Shutdown` and `ForceFlush` methods of the `"go.opentelemetry.io/otel/sdk/trace".TraceProvider` no longer return an error when no processor is registered. (#3268)
|
|
- The Prometheus exporter in `go.opentelemetry.io/otel/exporters/prometheus` cumulatively sums histogram buckets. (#3281)
|
|
- The sum of each histogram data point is now uniquely exported by the `go.opentelemetry.io/otel/exporters/otlpmetric` exporters. (#3284, #3293)
|
|
- Recorded values for asynchronous counters (`Counter` and `UpDownCounter`) are interpreted as exact, not incremental, sum values by the metric SDK. (#3350, #3278)
|
|
- `UpDownCounters` are now correctly output as Prometheus gauges in the `go.opentelemetry.io/otel/exporters/prometheus` exporter. (#3358)
|
|
- The Prometheus exporter in `go.opentelemetry.io/otel/exporters/prometheus` no longer describes the metrics it will send to Prometheus on startup.
|
|
Instead the exporter is defined as an "unchecked" collector for Prometheus.
|
|
This fixes the `reader is not registered` warning currently emitted on startup. (#3291 #3342)
|
|
- The `go.opentelemetry.io/otel/exporters/prometheus` exporter now correctly adds `_total` suffixes to counter metrics. (#3360)
|
|
- The `go.opentelemetry.io/otel/exporters/prometheus` exporter now adds a unit suffix to metric names.
|
|
This can be disabled using the `WithoutUnits()` option added to that package. (#3352)
|
|
|
|
## [1.11.0/0.32.3] 2022-10-12
|
|
|
|
### Added
|
|
|
|
- Add default User-Agent header to OTLP exporter requests (`go.opentelemetry.io/otel/exporters/otlptrace/otlptracegrpc` and `go.opentelemetry.io/otel/exporters/otlptrace/otlptracehttp`). (#3261)
|
|
|
|
### Changed
|
|
|
|
- `span.SetStatus` has been updated such that calls that lower the status are now no-ops. (#3214)
|
|
- Upgrade `golang.org/x/sys/unix` from `v0.0.0-20210423185535-09eb48e85fd7` to `v0.0.0-20220919091848-fb04ddd9f9c8`.
|
|
This addresses [GO-2022-0493](https://pkg.go.dev/vuln/GO-2022-0493). (#3235)
|
|
|
|
## [0.32.2] Metric SDK (Alpha) - 2022-10-11
|
|
|
|
### Added
|

|
- Added an example of using metric views to customize instruments. (#3177)
|
|
- Add default User-Agent header to OTLP exporter requests (`go.opentelemetry.io/otel/exporters/otlpmetric/otlpmetricgrpc` and `go.opentelemetry.io/otel/exporters/otlpmetric/otlpmetrichttp`). (#3261)
|
|
|
|
### Changed
|
|
|
|

|
|
- Encode the HTTP status code in the OpenTracing bridge (`go.opentelemetry.io/otel/bridge/opentracing`) as an integer. (#3265)
|
|
|
|
### Fixed
|
|
|
|
- Use default view if instrument does not match any registered view of a reader. (#3224, #3237)
|
|
- Return the same instrument every time a user makes the exact same instrument creation call. (#3229, #3251)
|
|
- Return the existing instrument when a view transforms a creation call to match an existing instrument. (#3240, #3251)
|
|
- Log a warning when a conflicting instrument (e.g. description, unit, data-type) is created instead of returning an error. (#3251)
|
|
- The OpenCensus bridge no longer sends empty batches of metrics. (#3263)
|
|
|
|

|
|
The method included in the renamed interface also changed from `LabelFilterFor` to `AttributeFilterFor`. (#2790)
|
|
- The `Metadata.Labels` method from the `go.opentelemetry.io/otel/sdk/metric/export` package is renamed to `Metadata.Attributes`.

## [0.29.0] - 2022-04-11
|
|
|
|
### Added
|
|
|
|
- The metrics global package was added back into several test files. (#2764)
|
|
- The `Meter` function is added back to the `go.opentelemetry.io/otel/metric/global` package.
|
|
This function is a convenience function equivalent to calling `global.MeterProvider().Meter(...)`. (#2750)
|
|
|
|
### Removed
|
|
|
|
- Removed module the `go.opentelemetry.io/otel/sdk/export/metric`.
|
|

This replaces the use of the now deprecated `InstrumentationLibrary` and `InstrumentationLibraryMetrics` types and fields in the proto library with the equivalent `InstrumentationScope` and `ScopeMetrics`. (#2748)
|
|
|
|
## [1.6.3] - 2022-04-07
|
|
|
|
### Fixed
|
|
|
|
- Allow non-comparable global `MeterProvider`, `TracerProvider`, and `TextMapPropagator` types to be set. (#2772, #2773)
|
|
|
|
## [1.6.2] - 2022-04-06
|
|
|
|
### Changed
|
|
|
|
- Don't panic anymore when setting a global TracerProvider or TextMapPropagator to itself. (#2749)
|
|
- Upgrade `go.opentelemetry.io/proto/otlp` in `go.opentelemetry.io/otel/exporters/otlp/otlptrace` from `v0.12.1` to `v0.15.0`.
|
|
This replaces the use of the now deprecated `InstrumentationLibrary` and `InstrumentationLibrarySpans` types and fields in the proto library with the equivalent `InstrumentationScope` and `ScopeSpans`. (#2748)
|
|
|
|
## [1.6.1] - 2022-03-28
|
|
|
|
### Fixed
|
|
|
|
- The `go.opentelemetry.io/otel/schema/*` packages now use the correct schema URL for their `SchemaURL` constant.
|
|
Instead of using `"https://opentelemetry.io/schemas/v<version>"` they now use the correct URL without a `v` prefix, `"https://opentelemetry.io/schemas/<version>"`. (#2743, #2744)
|
|
|
|
### Security
|
|
|
|
- Upgrade `go.opentelemetry.io/proto/otlp` from `v0.12.0` to `v0.12.1`.
|
|
This includes an indirect upgrade of `github.com/grpc-ecosystem/grpc-gateway` which resolves [a vulnerability](https://nvd.nist.gov/vuln/detail/CVE-2019-11254) from `gopkg.in/yaml.v2` in version `v2.2.3`. (#2724, #2728)
|
|
|
|
## [1.6.0/0.28.0] - 2022-03-23
|
|
|
|
### ⚠️ Notice ⚠️
|
|
|
|
This update is a breaking change of the unstable Metrics API.
|
|
Code instrumented with the `go.opentelemetry.io/otel/metric` will need to be modified.
|
|
|
|
### Added
|
|
|
|
- Add metrics exponential histogram support.
|
|
New mapping functions have been made available in `sdk/metric/aggregator/exponential/mapping` for other OpenTelemetry projects to take dependencies on. (#2502)
|
|
- Add Go 1.18 to our compatibility tests. (#2679)
|
|
- Allow configuring the Sampler with the `OTEL_TRACES_SAMPLER` and `OTEL_TRACES_SAMPLER_ARG` environment variables. (#2305, #2517)
|
|
- Add the `metric/global` for obtaining and setting the global `MeterProvider`. (#2660)
|
|
|
|
### Changed
|
|
|
|
- The metrics API has been significantly changed to match the revised OpenTelemetry specification.
|
|
High-level changes include:
|
|
|
|
- Synchronous and asynchronous instruments are now handled by independent `InstrumentProvider`s.
|
|
These `InstrumentProvider`s are managed with a `Meter`.
|
|
- Synchronous and asynchronous instruments are grouped into their own packages based on value types.
|
|
- Asynchronous callbacks can now be registered with a `Meter`.
|
|
|
|
Be sure to check out the metric module documentation for more information on how to use the revised API. (#2587, #2660)
|
|
|
|
### Fixed
|
|
|
|
- Fallback to general attribute limits when span specific ones are not set in the environment. (#2675, #2677)
|
|
|
|
## [1.5.0] - 2022-03-16
|
|
|
|
### Added
|
|
|
|
- Log the Exporters configuration in the TracerProviders message. (#2578)
|
|
- Added support to configure the span limits with environment variables.
|
|
The following environment variables are supported. (#2606, #2637)
|
|
- `OTEL_SPAN_ATTRIBUTE_VALUE_LENGTH_LIMIT`
|
|
- `OTEL_SPAN_ATTRIBUTE_COUNT_LIMIT`
|
|
- `OTEL_SPAN_EVENT_COUNT_LIMIT`
|
|
- `OTEL_EVENT_ATTRIBUTE_COUNT_LIMIT`
|
|
- `OTEL_SPAN_LINK_COUNT_LIMIT`
|
|
- `OTEL_LINK_ATTRIBUTE_COUNT_LIMIT`
|
|
|
|
If the provided environment variables are invalid (negative), the default values would be used.
|
|
- Rename the `gc` runtime name to `go` (#2560)
|
|
- Add resource container ID detection. (#2418)
|
|
- Add span attribute value length limit.
|
|
The new `AttributeValueLengthLimit` field is added to the `"go.opentelemetry.io/otel/sdk/trace".SpanLimits` type to configure this limit for a `TracerProvider`.
|
|
The default limit for this resource is "unlimited". (#2637)
|
|
- Add the `WithRawSpanLimits` option to `go.opentelemetry.io/otel/sdk/trace`.
|
|
This option replaces the `WithSpanLimits` option.
|
|
Zero or negative values will not be changed to the default value like `WithSpanLimits` does.
|
|
Setting a limit to zero will effectively disable the related resource it limits and setting to a negative value will mean that resource is unlimited.
|
|
Consequentially, limits should be constructed using `NewSpanLimits` and updated accordingly. (#2637)
|
|
|
|
### Changed
|
|
|
|
- Drop oldest tracestate `Member` when capacity is reached. (#2592)
|
|
- Add event and link drop counts to the exported data from the `oltptrace` exporter. (#2601)
|
|
- Unify path cleaning functionally in the `otlpmetric` and `otlptrace` configuration. (#2639)
|
|
- Change the debug message from the `sdk/trace.BatchSpanProcessor` to reflect the count is cumulative. (#2640)
|
|
- Introduce new internal `envconfig` package for OTLP exporters. (#2608)
|
|
- If `http.Request.Host` is empty, fall back to use `URL.Host` when populating `http.host` in the `semconv` packages. (#2661)
|
|
|
|
### Fixed
|
|
|
|
- Remove the OTLP trace exporter limit of SpanEvents when exporting. (#2616)
|
|
- Default to port `4318` instead of `4317` for the `otlpmetrichttp` and `otlptracehttp` client. (#2614, #2625)
|
|
- Unlimited span limits are now supported (negative values). (#2636, #2637)
|
|
|
|
### Deprecated
|
|
|
|
- Deprecated `"go.opentelemetry.io/otel/sdk/trace".WithSpanLimits`.
|
|
Use `WithRawSpanLimits` instead.
|
|
That option allows setting unlimited and zero limits, this option does not.
|
|
This option will be kept until the next major version incremented release. (#2637)
|
|
|
|
## [1.4.1] - 2022-02-16
|
|
|
|
### Fixed
|
|
|
|
- Fix race condition in reading the dropped spans number for the `BatchSpanProcessor`. (#2615)
|
|
|
|
## [1.4.0] - 2022-02-11
|
|
|
|
### Added
|
|
|
|
- Use `OTEL_EXPORTER_ZIPKIN_ENDPOINT` environment variable to specify zipkin collector endpoint. (#2490)
|
|
- Log the configuration of `TracerProvider`s, and `Tracer`s for debugging.
|
|
To enable use a logger with Verbosity (V level) `>=1`. (#2500)
|
|
- Added support to configure the batch span-processor with environment variables.
|
|
The following environment variables are used. (#2515)
|
|
- `OTEL_BSP_SCHEDULE_DELAY`
|
|
- `OTEL_BSP_EXPORT_TIMEOUT`
|
|
- `OTEL_BSP_MAX_QUEUE_SIZE`.
|
|
- `OTEL_BSP_MAX_EXPORT_BATCH_SIZE`
|
|
|
|
### Changed
|
|
|
|
- Zipkin exporter exports `Resource` attributes in the `Tags` field. (#2589)
|
|
|
|
### Deprecated
|
|
|
|
- Deprecate module the `go.opentelemetry.io/otel/sdk/export/metric`.
|
|
Use the `go.opentelemetry.io/otel/sdk/metric` module instead. (#2382)
|
|
- Deprecate `"go.opentelemetry.io/otel/sdk/metric".AtomicFieldOffsets`. (#2445)
|
|
|
|
### Fixed
|
|
|
|
- Fixed the instrument kind for noop async instruments to correctly report an implementation. (#2461)
|
|
- Fix UDP packets overflowing with Jaeger payloads. (#2489, #2512)
|
|
- Change the `otlpmetric.Client` interface's `UploadMetrics` method to accept a single `ResourceMetrics` instead of a slice of them. (#2491)
|
|
- Specify explicit buckets in Prometheus example, fixing issue where example only has `+inf` bucket. (#2419, #2493)
|
|
- W3C baggage will now decode urlescaped values. (#2529)
|
|
- Baggage members are now only validated once, when calling `NewMember` and not also when adding it to the baggage itself. (#2522)
|
|
- The order attributes are dropped from spans in the `go.opentelemetry.io/otel/sdk/trace` package when capacity is reached is fixed to be in compliance with the OpenTelemetry specification.
|
|
Instead of dropping the least-recently-used attribute, the last added attribute is dropped.
|
|
This drop order still only applies to attributes with unique keys not already contained in the span.
|
|
If an attribute is added with a key already contained in the span, that attribute is updated to the new value being added. (#2576)
|
|
|
|
### Removed
|
|
|
|
- Updated `go.opentelemetry.io/proto/otlp` from `v0.11.0` to `v0.12.0`. This version removes a number of deprecated methods. (#2546)
|
|
- [`Metric.GetIntGauge()`](https://pkg.go.dev/go.opentelemetry.io/proto/otlp@v0.11.0/metrics/v1#Metric.GetIntGauge)
|
|
- [`Metric.GetIntHistogram()`](https://pkg.go.dev/go.opentelemetry.io/proto/otlp@v0.11.0/metrics/v1#Metric.GetIntHistogram)
|
|
- [`Metric.GetIntSum()`](https://pkg.go.dev/go.opentelemetry.io/proto/otlp@v0.11.0/metrics/v1#Metric.GetIntSum)
|
|
|
|
## [1.3.0] - 2021-12-10
|
|
|
|
### ⚠️ Notice ⚠️
|
|
|
|
We have updated the project minimum supported Go version to 1.16
|
|
|
|
### Added
|
|
|
|
- Added an internal Logger.
|
|
This can be used by the SDK and API to provide users with feedback of the internal state.
|
|
To enable verbose logs configure the logger which will print V(1) logs. For debugging information configure to print V(5) logs. (#2343)
|
|
- Add the `WithRetry` `Option` and the `RetryConfig` type to the `go.opentelemetry.io/otel/exporter/otel/otlpmetric/otlpmetrichttp` package to specify retry behavior consistently. (#2425)
|
|
- Add `SpanStatusFromHTTPStatusCodeAndSpanKind` to all `semconv` packages to return a span status code similar to `SpanStatusFromHTTPStatusCode`, but exclude `4XX` HTTP errors as span errors if the span is of server kind. (#2296)
|
|
|
|
### Changed
|
|
|
|
- The `"go.opentelemetry.io/otel/exporter/otel/otlptrace/otlptracegrpc".Client` now uses the underlying gRPC `ClientConn` to handle name resolution, TCP connection establishment (with retries and backoff) and TLS handshakes, and handling errors on established connections by re-resolving the name and reconnecting. (#2329)
|
|
- The `"go.opentelemetry.io/otel/exporter/otel/otlpmetric/otlpmetricgrpc".Client` now uses the underlying gRPC `ClientConn` to handle name resolution, TCP connection establishment (with retries and backoff) and TLS handshakes, and handling errors on established connections by re-resolving the name and reconnecting. (#2425)
|
|
- The `"go.opentelemetry.io/otel/exporter/otel/otlpmetric/otlpmetricgrpc".RetrySettings` type is renamed to `RetryConfig`. (#2425)
|
|
- The `go.opentelemetry.io/otel/exporter/otel/*` gRPC exporters now default to using the host's root CA set if none are provided by the user and `WithInsecure` is not specified. (#2432)
|
|
- Change `resource.Default` to be evaluated the first time it is called, rather than on import. This allows the caller the option to update `OTEL_RESOURCE_ATTRIBUTES` first, such as with `os.Setenv`. (#2371)
|
|
|
|
### Fixed
|
|
|
|
- The `go.opentelemetry.io/otel/exporter/otel/*` exporters are updated to handle per-signal and universal endpoints according to the OpenTelemetry specification.
|
|
Any per-signal endpoint set via an `OTEL_EXPORTER_OTLP_<signal>_ENDPOINT` environment variable is now used without modification of the path.
|
|
When `OTEL_EXPORTER_OTLP_ENDPOINT` is set, if it contains a path, that path is used as a base path which per-signal paths are appended to. (#2433)
|
|
- Basic metric controller updated to use sync.Map to avoid blocking calls (#2381)
|
|
- The `go.opentelemetry.io/otel/exporter/jaeger` correctly sets the `otel.status_code` value to be a string of `ERROR` or `OK` instead of an integer code. (#2439, #2440)
|
|
|
|
### Deprecated
|
|
|
|
- Deprecated the `"go.opentelemetry.io/otel/exporter/otel/otlpmetric/otlpmetrichttp".WithMaxAttempts` `Option`, use the new `WithRetry` `Option` instead. (#2425)
|
|
- Deprecated the `"go.opentelemetry.io/otel/exporter/otel/otlpmetric/otlpmetrichttp".WithBackoff` `Option`, use the new `WithRetry` `Option` instead. (#2425)
|
|
|
|
### Removed
|
|
|
|
- Remove the metric Processor's ability to convert cumulative to delta aggregation temporality. (#2350)
|
|
- Remove the metric Bound Instruments interface and implementations. (#2399)
|
|
- Remove the metric MinMaxSumCount kind aggregation and the corresponding OTLP export path. (#2423)
|
|
- Metric SDK removes the "exact" aggregator for histogram instruments, as it performed a non-standard aggregation for OTLP export (creating repeated Gauge points) and worked its way into a number of confusing examples. (#2348)
|
|
|
|
## [1.2.0] - 2021-11-12
|
|
|
|
### Changed
|
|
|
|
- Metric SDK `export.ExportKind`, `export.ExportKindSelector` types have been renamed to `aggregation.Temporality` and `aggregation.TemporalitySelector` respectively to keep in line with current specification and protocol along with built-in selectors (e.g., `aggregation.CumulativeTemporalitySelector`, ...). (#2274)
|
|
- The Metric `Exporter` interface now requires a `TemporalitySelector` method instead of an `ExportKindSelector`. (#2274)
|
|
- Metrics API cleanup. The `metric/sdkapi` package has been created to relocate the API-to-SDK interface:
|
|
- The following interface types simply moved from `metric` to `metric/sdkapi`: `Descriptor`, `MeterImpl`, `InstrumentImpl`, `SyncImpl`, `BoundSyncImpl`, `AsyncImpl`, `AsyncRunner`, `AsyncSingleRunner`, and `AsyncBatchRunner`
|
|
- The following struct types moved and are replaced with type aliases, since they are exposed to the user: `Observation`, `Measurement`.
|
|
- The No-op implementations of sync and async instruments are no longer exported, new functions `sdkapi.NewNoopAsyncInstrument()` and `sdkapi.NewNoopSyncInstrument()` are provided instead. (#2271)

## [1.1.0] - 2021-10-27
|
|
|
|
### Added
|
|

|
- Add the `go.opentelemetry.io/otel/semconv/v1.5.0` package.
|
|
The package contains semantic conventions from the `v1.5.0` version of the OpenTelemetry specification. (#2322)

|
|
|
|
### Fixed
|
|
|
|
- The `"go.opentelemetry.io/otel/semconv/v1.4.0".HTTPServerAttributesFromHTTPRequest` now correctly only sets the HTTP client IP attribute even if the connection was routed with proxies and there are multiple addresses in the `X-Forwarded-For` header. (#2282, #2284)
|
|
- The `"go.opentelemetry.io/otel/semconv/v1.4.0".NetAttributesFromHTTPRequest` function correctly handles IPv6 addresses as IP addresses and sets the correct net peer IP instead of the net peer hostname attribute. (#2283, #2285)
|
|
- The simple span processor shutdown method deterministically returns the exporter error status if it simultaneously finishes when the deadline is reached. (#2290, #2289)

|
|
|
|

|
|
|
|
- OTLP trace exporter now sets the `SchemaURL` field in the exported telemetry if the Tracer has `WithSchemaURL` option. (#2242)
|
|
|
|
### Fixed
|

|
|
- Slice-valued attributes can correctly be used as map keys. (#2223)
|
|

|
|
- Removed the deprecated package `go.opentelemetry.io/otel/oteltest`. (#2234)

## [1.0.0-RC3] - 2021-09-02
|
|
|
|
### Added
|
|
|
|
- Added `ErrorHandlerFunc` to use a function as an `"go.opentelemetry.io/otel".ErrorHandler`. (#2149)
|
|
- Added `"go.opentelemetry.io/otel/trace".WithStackTrace` option to add a stack trace when using `span.RecordError` or when panic is handled in `span.End`. (#2163)
|
|
- Added typed slice attribute types and functionality to the `go.opentelemetry.io/otel/attribute` package to replace the existing array type and functions. (#2162)
|
|
- `BoolSlice`, `IntSlice`, `Int64Slice`, `Float64Slice`, and `StringSlice` replace the use of the `Array` function in the package.
|
|
- Added the `go.opentelemetry.io/otel/example/fib` example package.
|
|
Included is an example application that computes Fibonacci numbers. (#2203)
|
|
|
|
### Changed
|
|
|
|
- Metric instruments have been renamed to match the (feature-frozen) metric API specification:
|
|
- ValueRecorder becomes Histogram
|
|
- ValueObserver becomes Gauge
|
|
- SumObserver becomes CounterObserver
|
|
- UpDownSumObserver becomes UpDownCounterObserver
|
|
The API exported from this project is still considered experimental. (#2202)
|
|
- Metric SDK/API implementation type `InstrumentKind` moves into `sdkapi` sub-package. (#2091)
|
|
- The Metrics SDK export record no longer contains a Resource pointer, the SDK `"go.opentelemetry.io/otel/sdk/trace/export/metric".Exporter.Export()` function for push-based exporters now takes a single Resource argument, pull-based exporters use `"go.opentelemetry.io/otel/sdk/metric/controller/basic".Controller.Resource()`. (#2120)
|
|
- The JSON output of the `go.opentelemetry.io/otel/exporters/stdout/stdouttrace` is harmonized now such that the output is "plain" JSON objects after each other of the form `{ ... } { ... } { ... }`. Earlier the JSON objects describing a span were wrapped in a slice for each `Exporter.ExportSpans` call, like `[ { ... } ][ { ... } { ... } ]`. Outputting JSON object directly after each other is consistent with JSON loggers, and a bit easier to parse and read. (#2196)
|
|
- Update the `NewTracerConfig`, `NewSpanStartConfig`, `NewSpanEndConfig`, and `NewEventConfig` function in the `go.opentelemetry.io/otel/trace` package to return their respective configurations as structs instead of pointers to the struct. (#2212)
|
|
|
|
### Deprecated
|
|
|
|
- The `go.opentelemetry.io/otel/bridge/opencensus/utils` package is deprecated.
|
|
All functionality from this package now exists in the `go.opentelemetry.io/otel/bridge/opencensus` package.
|
|
The functions from that package should be used instead. (#2166)
|
|
- The `"go.opentelemetry.io/otel/attribute".Array` function and the related `ARRAY` value type is deprecated.
|
|
Use the typed `*Slice` functions and types added to the package instead. (#2162)
|
|
- The `"go.opentelemetry.io/otel/attribute".Any` function is deprecated.
|
|
Use the typed functions instead. (#2181)
|
|
- The `go.opentelemetry.io/otel/oteltest` package is deprecated.
|
|
The `"go.opentelemetry.io/otel/sdk/trace/tracetest".SpanRecorder` can be registered with the default SDK (`go.opentelemetry.io/otel/sdk/trace`) as a `SpanProcessor` and used as a replacement for this deprecated package. (#2188)
|
|
|
|
### Removed
|
|
|
|
- Removed metrics test package `go.opentelemetry.io/otel/sdk/export/metric/metrictest`. (#2105)
|
|
|
|
### Fixed
|
|
|
|
- The `fromEnv` detector no longer throws an error when `OTEL_RESOURCE_ATTRIBUTES` environment variable is not set or empty. (#2138)
|
|
- Setting the global `ErrorHandler` with `"go.opentelemetry.io/otel".SetErrorHandler` multiple times is now supported. (#2160, #2140)
|
|
- The `"go.opentelemetry.io/otel/attribute".Any` function now supports `int32` values. (#2169)
|
|
- Multiple calls to `"go.opentelemetry.io/otel/sdk/metric/controller/basic".WithResource()` are handled correctly, and when no resources are provided `"go.opentelemetry.io/otel/sdk/resource".Default()` is used. (#2120)
|
|
- The `WithoutTimestamps` option for the `go.opentelemetry.io/otel/exporters/stdout/stdouttrace` exporter causes the exporter to correctly omit timestamps. (#2195)
|
|
- Fixed typos in resources.go. (#2201)
|
|
|
|
## [1.0.0-RC2] - 2021-07-26
|
|
|
|
### Added
|
|
|
|
- Added `WithOSDescription` resource configuration option to set OS (Operating System) description resource attribute (`os.description`). (#1840)
|
|
- Added `WithOS` resource configuration option to set all OS (Operating System) resource attributes at once. (#1840)
|
|
- Added the `WithRetry` option to the `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp` package.
|
|
This option is a replacement for the removed `WithMaxAttempts` and `WithBackoff` options. (#2095)
|
|
- Added API `LinkFromContext` to return Link which encapsulates SpanContext from provided context and also encapsulates attributes. (#2115)
|
|
- Added a new `Link` type under the SDK `otel/sdk/trace` package that counts the number of attributes that were dropped for surpassing the `AttributePerLinkCountLimit` configured in the Span's `SpanLimits`.
|
|
This new type replaces the equal-named API `Link` type found in the `otel/trace` package for most usages within the SDK.
|
|
For example, instances of this type are now returned by the `Links()` function of `ReadOnlySpan`s provided in places like the `OnEnd` function of `SpanProcessor` implementations. (#2118)
|
|
- Added the `SpanRecorder` type to the `go.opentelemetry.io/otel/skd/trace/tracetest` package.
|
|
This type can be used with the default SDK as a `SpanProcessor` during testing. (#2132)
|
|
|
|
### Changed
|
|
|
|
- The `SpanModels` function is now exported from the `go.opentelemetry.io/otel/exporters/zipkin` package to convert OpenTelemetry spans into Zipkin model spans. (#2027)
|
|
- Rename the `"go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc".RetrySettings` to `RetryConfig`. (#2095)
|
|
|
|
### Deprecated
|
|
|
|
- The `TextMapCarrier` and `TextMapPropagator` from the `go.opentelemetry.io/otel/oteltest` package and their associated creation functions (`TextMapCarrier`, `NewTextMapPropagator`) are deprecated. (#2114)
|
|
- The `Harness` type from the `go.opentelemetry.io/otel/oteltest` package and its associated creation function, `NewHarness` are deprecated and will be removed in the next release. (#2123)
|
|
- The `TraceStateFromKeyValues` function from the `go.opentelemetry.io/otel/oteltest` package is deprecated.
|
|
Use the `trace.ParseTraceState` function instead. (#2122)
|
|
|
|
### Removed
|
|
|
|
- Removed the deprecated package `go.opentelemetry.io/otel/exporters/trace/jaeger`. (#2020)
|
|
- Removed the deprecated package `go.opentelemetry.io/otel/exporters/trace/zipkin`. (#2020)
|
|
- Removed the `"go.opentelemetry.io/otel/sdk/resource".WithBuiltinDetectors` function.
|
|
The explicit `With*` options for every built-in detector should be used instead. (#2026 #2097)
|
|
- Removed the `WithMaxAttempts` and `WithBackoff` options from the `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp` package.
|
|
The retry logic of the package has been updated to match the `otlptracegrpc` package and accordingly a `WithRetry` option is added that should be used instead. (#2095)
|
|
- Removed `DroppedAttributeCount` field from `otel/trace.Link` struct. (#2118)
|
|
|
|
### Fixed
|
|
|
|
- When using WithNewRoot, don't use the parent context for making sampling decisions. (#2032)
|
|
- `oteltest.Tracer` now creates a valid `SpanContext` when using `WithNewRoot`. (#2073)
|
|
- OS type detector now sets the correct `dragonflybsd` value for DragonFly BSD. (#2092)
|
|
- The OTel span status is correctly transformed into the OTLP status in the `go.opentelemetry.io/otel/exporters/otlp/otlptrace` package.
|
|
This fix will by default set the status to `Unset` if it is not explicitly set to `Ok` or `Error`. (#2099 #2102)
|
|
- The `Inject` method for the `"go.opentelemetry.io/otel/propagation".TraceContext` type no longer injects empty `tracestate` values. (#2108)
|
|
- Use `6831` as default Jaeger agent port instead of `6832`. (#2131)
|
|
|
|

|
|
|
## [1.0.0-RC1] / 0.21.0 - 2021-06-18
|
|
|
|
With this release we are introducing a split in module versions. The tracing API and SDK are entering the `v1.0.0` Release Candidate phase with `v1.0.0-RC1`
|
|
while the experimental metrics API and SDK continue with `v0.x` releases at `v0.21.0`. Modules at major version 1 or greater will not depend on modules
|
|
with major version 0.
|
|
|
|
### Added
|
|
|
|
- Adds `otlpgrpc.WithRetry`option for configuring the retry policy for transient errors on the otlp/gRPC exporter. (#1832)
|
|
- The following status codes are defined as transient errors:
|
|
| gRPC Status Code | Description |
|
|
| ---------------- | ----------- |
|
|
| 1 | Cancelled |
|
|
| 4 | Deadline Exceeded |
|
|
| 8 | Resource Exhausted |
|
|
| 10 | Aborted |
|

| 10 | Out of Range |
|
|
| 14 | Unavailable |
|
|
| 15 | Data Loss |
|
|
- Added `Status` type to the `go.opentelemetry.io/otel/sdk/trace` package to represent the status of a span. (#1874)
|
|
- Added `SpanStub` type and its associated functions to the `go.opentelemetry.io/otel/sdk/trace/tracetest` package.
|
|
This type can be used as a testing replacement for the `SpanSnapshot` that was removed from the `go.opentelemetry.io/otel/sdk/trace` package. (#1873)
|
|
- Adds support for scheme in `OTEL_EXPORTER_OTLP_ENDPOINT` according to the spec. (#1886)
|
|
- Adds `trace.WithSchemaURL` option for configuring the tracer with a Schema URL. (#1889)
|
|
- Added an example of using OpenTelemetry Go as a trace context forwarder. (#1912)
|
|
- `ParseTraceState` is added to the `go.opentelemetry.io/otel/trace` package.
|
|
It can be used to decode a `TraceState` from a `tracestate` header string value. (#1937)
|
|
- Added `Len` method to the `TraceState` type in the `go.opentelemetry.io/otel/trace` package.
|
|
This method returns the number of list-members the `TraceState` holds. (#1937)
|
|
- Creates package `go.opentelemetry.io/otel/exporters/otlp/otlptrace` that defines a trace exporter that uses a `otlptrace.Client` to send data.
|
|
Creates package `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc` implementing a gRPC `otlptrace.Client` and offers convenience functions, `NewExportPipeline` and `InstallNewPipeline`, to setup and install a `otlptrace.Exporter` in tracing .(#1922)
|
|
- Added `Baggage`, `Member`, and `Property` types to the `go.opentelemetry.io/otel/baggage` package along with their related functions. (#1967)
|
|
- Added `ContextWithBaggage`, `ContextWithoutBaggage`, and `FromContext` functions to the `go.opentelemetry.io/otel/baggage` package.
|
|
These functions replace the `Set`, `Value`, `ContextWithValue`, `ContextWithoutValue`, and `ContextWithEmpty` functions from that package and directly work with the new `Baggage` type. (#1967)
|
|
- The `OTEL_SERVICE_NAME` environment variable is the preferred source for `service.name`, used by the environment resource detector if a service name is present both there and in `OTEL_RESOURCE_ATTRIBUTES`. (#1969)
|
|
- Creates package `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp` implementing an HTTP `otlptrace.Client` and offers convenience functions, `NewExportPipeline` and `InstallNewPipeline`, to setup and install a `otlptrace.Exporter` in tracing. (#1963)
|
|
- Changes `go.opentelemetry.io/otel/sdk/resource.NewWithAttributes` to require a schema URL. The old function is still available as `resource.NewSchemaless`. This is a breaking change. (#1938)
|
|
- Several builtin resource detectors now correctly populate the schema URL. (#1938)
|
|
- Creates package `go.opentelemetry.io/otel/exporters/otlp/otlpmetric` that defines a metrics exporter that uses a `otlpmetric.Client` to send data.
|
|
- Creates package `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc` implementing a gRPC `otlpmetric.Client` and offers convenience functions, `New` and `NewUnstarted`, to create an `otlpmetric.Exporter`.(#1991)
|
|
- Added `go.opentelemetry.io/otel/exporters/stdout/stdouttrace` exporter. (#2005)
|
|
- Added `go.opentelemetry.io/otel/exporters/stdout/stdoutmetric` exporter. (#2005)
|
|
- Added a `TracerProvider()` method to the `"go.opentelemetry.io/otel/trace".Span` interface. This can be used to obtain a `TracerProvider` from a given span that utilizes the same trace processing pipeline. (#2009)
|
|
|
|
### Changed
|
|
|
|
- Make `NewSplitDriver` from `go.opentelemetry.io/otel/exporters/otlp` take variadic arguments instead of a `SplitConfig` item.
|
|
`NewSplitDriver` now automatically implements an internal `noopDriver` for `SplitConfig` fields that are not initialized. (#1798)
|
|
- `resource.New()` now creates a Resource without builtin detectors. Previous behavior is now achieved by using `WithBuiltinDetectors` Option. (#1810)
|
|
- Move the `Event` type from the `go.opentelemetry.io/otel` package to the `go.opentelemetry.io/otel/sdk/trace` package. (#1846)
|
|
- CI builds validate against last two versions of Go, dropping 1.14 and adding 1.16. (#1865)
|
|
- BatchSpanProcessor now report export failures when calling `ForceFlush()` method. (#1860)
|
|
- `Set.Encoded(Encoder)` no longer caches the result of an encoding. (#1855)
|
|
- Renamed `CloudZoneKey` to `CloudAvailabilityZoneKey` in Resource semantic conventions according to spec. (#1871)
|
|
- The `StatusCode` and `StatusMessage` methods of the `ReadOnlySpan` interface and the `Span` produced by the `go.opentelemetry.io/otel/sdk/trace` package have been replaced with a single `Status` method.
|
|
This method returns the status of a span using the new `Status` type. (#1874)
|
|
- Updated `ExportSpans` method of the`SpanExporter` interface type to accept `ReadOnlySpan`s instead of the removed `SpanSnapshot`.
|
|
This brings the export interface into compliance with the specification in that it now accepts an explicitly immutable type instead of just an implied one. (#1873)
|
|
- Unembed `SpanContext` in `Link`. (#1877)
|
|
- Generate Semantic conventions from the specification YAML. (#1891)
|
|
- Spans created by the global `Tracer` obtained from `go.opentelemetry.io/otel`, prior to a functioning `TracerProvider` being set, now propagate the span context from their parent if one exists. (#1901)
|
|
- The `"go.opentelemetry.io/otel".Tracer` function now accepts tracer options. (#1902)
|
|
- Move the `go.opentelemetry.io/otel/unit` package to `go.opentelemetry.io/otel/metric/unit`. (#1903)
|
|
- Changed `go.opentelemetry.io/otel/trace.TracerConfig` to conform to the [Contributing guidelines](CONTRIBUTING.md#config.) (#1921)
|
|
- Changed `go.opentelemetry.io/otel/trace.SpanConfig` to conform to the [Contributing guidelines](CONTRIBUTING.md#config). (#1921)
|
|
- Changed `span.End()` now only accepts Options that are allowed at `End()`. (#1921)
|
|
- Changed `go.opentelemetry.io/otel/metric.InstrumentConfig` to conform to the [Contributing guidelines](CONTRIBUTING.md#config). (#1921)
|
|
- Changed `go.opentelemetry.io/otel/metric.MeterConfig` to conform to the [Contributing guidelines](CONTRIBUTING.md#config). (#1921)
|
|
- Refactored option types according to the contribution style guide. (#1882)
|
|
- Move the `go.opentelemetry.io/otel/trace.TraceStateFromKeyValues` function to the `go.opentelemetry.io/otel/oteltest` package.
|
|
This function is preserved for testing purposes where it may be useful to create a `TraceState` from `attribute.KeyValue`s, but it is not intended for production use.
|
|
The new `ParseTraceState` function should be used to create a `TraceState`. (#1931)
|
|
- Updated `MarshalJSON` method of the `go.opentelemetry.io/otel/trace.TraceState` type to marshal the type into the string representation of the `TraceState`. (#1931)
|
|
- The `TraceState.Delete` method from the `go.opentelemetry.io/otel/trace` package no longer returns an error in addition to a `TraceState`. (#1931)
|
|
- Updated `Get` method of the `TraceState` type from the `go.opentelemetry.io/otel/trace` package to accept a `string` instead of an `attribute.Key` type. (#1931)

|
|
- Renamed `NewExporter` to `New` in the `go.opentelemetry.io/otel/exporters/metric/prometheus` package. (#1985)
|
|
- Renamed `NewExporter` to `New` in the `go.opentelemetry.io/otel/exporters/trace/jaeger` package. (#1985)
|
|
- Renamed `NewExporter` to `New` in the `go.opentelemetry.io/otel/exporters/trace/zipkin` package. (#1985)
|
|
- Renamed `NewExporter` to `New` in the `go.opentelemetry.io/otel/exporters/otlp` package. (#1985)
|

|
|
- The `go.opentelemetry.io/otel/semconv` package has been moved to `go.opentelemetry.io/otel/semconv/v1.4.0` to allow for multiple [telemetry schema](https://github.com/open-telemetry/oteps/blob/main/text/0152-telemetry-schemas.md) versions to be used concurrently. (#1987)
|
|
- Metrics test helpers in `go.opentelemetry.io/otel/oteltest` have been moved to `go.opentelemetry.io/otel/metric/metrictest`. (#1988)
|
|
|
|
### Deprecated
|
|
|
|
- The `go.opentelemetry.io/otel/exporters/metric/prometheus` is deprecated, use `go.opentelemetry.io/otel/exporters/prometheus` instead. (#1993)
|
|
- The `go.opentelemetry.io/otel/exporters/trace/jaeger` is deprecated, use `go.opentelemetry.io/otel/exporters/jaeger` instead. (#1993)
|
|
- The `go.opentelemetry.io/otel/exporters/trace/zipkin` is deprecated, use `go.opentelemetry.io/otel/exporters/zipkin` instead. (#1993)
|
|
|
|
### Removed
|
|
|
|
- Removed `resource.WithoutBuiltin()`. Use `resource.New()`. (#1810)
|
|
- Unexported types `resource.FromEnv`, `resource.Host`, and `resource.TelemetrySDK`, Use the corresponding `With*()` to use individually. (#1810)
|
|
- Removed the `Tracer` and `IsRecording` method from the `ReadOnlySpan` in the `go.opentelemetry.io/otel/sdk/trace`.
|
|
The `Tracer` method is not a required to be included in this interface and given the mutable nature of the tracer that is associated with a span, this method is not appropriate.
|
|
The `IsRecording` method returns if the span is recording or not.
|
|
A read-only span value does not need to know if updates to it will be recorded or not.
|
|
By definition, it cannot be updated so there is no point in communicating if an update is recorded. (#1873)
|
|
- Removed the `SpanSnapshot` type from the `go.opentelemetry.io/otel/sdk/trace` package.
|
|
The use of this type has been replaced with the use of the explicitly immutable `ReadOnlySpan` type.
|
|
When a concrete representation of a read-only span is needed for testing, the newly added `SpanStub` in the `go.opentelemetry.io/otel/sdk/trace/tracetest` package should be used. (#1873)
|
|
- Removed the `Tracer` method from the `Span` interface in the `go.opentelemetry.io/otel/trace` package.
|
|
Using the same tracer that created a span introduces the error where an instrumentation library's `Tracer` is used by other code instead of their own.
|
|
The `"go.opentelemetry.io/otel".Tracer` function or a `TracerProvider` should be used to acquire a library specific `Tracer` instead. (#1900)
|
|
- The `TracerProvider()` method on the `Span` interface may also be used to obtain a `TracerProvider` using the same trace processing pipeline. (#2009)
|
|
- The `http.url` attribute generated by `HTTPClientAttributesFromHTTPRequest` will no longer include username or password information. (#1919)
|
|
- Removed `IsEmpty` method of the `TraceState` type in the `go.opentelemetry.io/otel/trace` package in favor of using the added `TraceState.Len` method. (#1931)
|
|
- Removed `Set`, `Value`, `ContextWithValue`, `ContextWithoutValue`, and `ContextWithEmpty` functions in the `go.opentelemetry.io/otel/baggage` package.
|
|
Handling of baggage is now done using the added `Baggage` type and related context functions (`ContextWithBaggage`, `ContextWithoutBaggage`, and `FromContext`) in that package. (#1967)
|
|
- The `InstallNewPipeline` and `NewExportPipeline` creation functions in all the exporters (prometheus, otlp, stdout, jaeger, and zipkin) have been removed.
|
|
These functions were deemed premature attempts to provide convenience that did not achieve this aim. (#1985)
|
|
- The `go.opentelemetry.io/otel/exporters/otlp` exporter has been removed. Use `go.opentelemetry.io/otel/exporters/otlp/otlptrace` instead. (#1990)
|
|
- The `go.opentelemetry.io/otel/exporters/stdout` exporter has been removed. Use `go.opentelemetry.io/otel/exporters/stdout/stdouttrace` or `go.opentelemetry.io/otel/exporters/stdout/stdoutmetric` instead. (#2005)
|
|
|
|
### Fixed
|
|
|
|
- Only report errors from the `"go.opentelemetry.io/otel/sdk/resource".Environment` function when they are not `nil`. (#1850, #1851)
|
|
- The `Shutdown` method of the simple `SpanProcessor` in the `go.opentelemetry.io/otel/sdk/trace` package now honors the context deadline or cancellation. (#1616, #1856)
|
|
- BatchSpanProcessor now drops span batches that failed to be exported. (#1860)
|
|
- Use `http://localhost:14268/api/traces` as default Jaeger collector endpoint instead of `http://localhost:14250`. (#1898)
|
|
- Allow trailing and leading whitespace in the parsing of a `tracestate` header. (#1931)
|
|
- Add logic to determine if the channel is closed to fix Jaeger exporter test panic with close closed channel. (#1870, #1973)
|
|
- Avoid transport security when OTLP endpoint is a Unix socket. (#2001)
|
|
|
|
### Security
|
|
|
|
## [0.20.0] - 2021-04-23
|
|
|
|
### Added
|
|
|
|
- The OTLP exporter now has two new convenience functions, `NewExportPipeline` and `InstallNewPipeline`, setup and install the exporter in tracing and metrics pipelines. (#1373)
|
|
- Adds semantic conventions for exceptions. (#1492)
|
|
- Added Jaeger Environment variables: `OTEL_EXPORTER_JAEGER_AGENT_HOST`, `OTEL_EXPORTER_JAEGER_AGENT_PORT`
|
|
These environment variables can be used to override Jaeger agent hostname and port (#1752)
|
|
- Option `ExportTimeout` was added to batch span processor. (#1755)
|
|
- `trace.TraceFlags` is now a defined type over `byte` and `WithSampled(bool) TraceFlags` and `IsSampled() bool` methods have been added to it. (#1770)
|
|
- The `Event` and `Link` struct types from the `go.opentelemetry.io/otel` package now include a `DroppedAttributeCount` field to record the number of attributes that were not recorded due to configured limits being reached. (#1771)
|
|
- The Jaeger exporter now reports dropped attributes for a Span event in the exported log. (#1771)
|
|
- Adds test to check BatchSpanProcessor ignores `OnEnd` and `ForceFlush` post `Shutdown`. (#1772)
|
|
- Extract resource attributes from the `OTEL_RESOURCE_ATTRIBUTES` environment variable and merge them with the `resource.Default` resource as well as resources provided to the `TracerProvider` and metric `Controller`. (#1785)
|
|
- Added `WithOSType` resource configuration option to set OS (Operating System) type resource attribute (`os.type`). (#1788)
|
|
- Added `WithProcess*` resource configuration options to set Process resource attributes. (#1788)
|
|
- `process.pid`
|
|
- `process.executable.name`
|
|
- `process.executable.path`
|
|
- `process.command_args`
|
|
- `process.owner`
|
|
- `process.runtime.name`
|
|
- `process.runtime.version`
|
|
- `process.runtime.description`
|
|
- Adds `k8s.node.name` and `k8s.node.uid` attribute keys to the `semconv` package. (#1789)
|
|
- Added support for configuring OTLP/HTTP and OTLP/gRPC Endpoints, TLS Certificates, Headers, Compression and Timeout via Environment Variables. (#1758, #1769 and #1811)
|
|
- `OTEL_EXPORTER_OTLP_ENDPOINT`
|
|
- `OTEL_EXPORTER_OTLP_TRACES_ENDPOINT`
|
|
- `OTEL_EXPORTER_OTLP_METRICS_ENDPOINT`
|
|
- `OTEL_EXPORTER_OTLP_HEADERS`
|
|
- `OTEL_EXPORTER_OTLP_TRACES_HEADERS`
|
|
- `OTEL_EXPORTER_OTLP_METRICS_HEADERS`
|
|
- `OTEL_EXPORTER_OTLP_COMPRESSION`
|
|
- `OTEL_EXPORTER_OTLP_TRACES_COMPRESSION`
|
|
- `OTEL_EXPORTER_OTLP_METRICS_COMPRESSION`
|
|
- `OTEL_EXPORTER_OTLP_TIMEOUT`
|
|
- `OTEL_EXPORTER_OTLP_TRACES_TIMEOUT`
|
|
- `OTEL_EXPORTER_OTLP_METRICS_TIMEOUT`

|
- `OTEL_EXPORTER_OTLP_CERTIFICATE`
|
|
- `OTEL_EXPORTER_OTLP_TRACES_CERTIFICATE`
|
|

|
|
- Adds `otlpgrpc.WithTimeout` option for configuring timeout to the otlp/gRPC exporter. (#1821)
|
|
- Adds `jaeger.WithMaxPacketSize` option for configuring maximum UDP packet size used when connecting to the Jaeger agent. (#1853)
|
|
|
|
### Fixed
|
|
|
|
- The `Span.IsRecording` implementation from `go.opentelemetry.io/otel/sdk/trace` always returns false when not being sampled. (#1750)
|
|
- The Jaeger exporter now correctly sets tags for the Span status code and message.
|
|
This means it uses the correct tag keys (`"otel.status_code"`, `"otel.status_description"`) and does not set the status message as a tag unless it is set on the span. (#1761)
|
|
- The Jaeger exporter now correctly records Span event's names using the `"event"` key for a tag.
|
|
Additionally, this tag is overridden, as specified in the OTel specification, if the event contains an attribute with that key. (#1768)
|
|
- Zipkin Exporter: Ensure mapping between OTel and Zipkin span data complies with the specification. (#1688)
|
|
- Fixed typo for default service name in Jaeger Exporter. (#1797)
|
|
- Fix flaky OTLP for the reconnnection of the client connection. (#1527, #1814)
|
|
- Fix Jaeger exporter dropping of span batches that exceed the UDP packet size limit.
|
|
Instead, the exporter now splits the batch into smaller sendable batches. (#1828)
|
|
|
|
### Changed
|
|
|
|
- Span `RecordError` now records an `exception` event to comply with the semantic convention specification. (#1492)
|
|
- Jaeger exporter was updated to use thrift v0.14.1. (#1712)
|
|
- Migrate from using internally built and maintained version of the OTLP to the one hosted at `go.opentelemetry.io/proto/otlp`. (#1713)
|
|
- Migrate from using `github.com/gogo/protobuf` to `google.golang.org/protobuf` to match `go.opentelemetry.io/proto/otlp`. (#1713)
|
|
- The storage of a local or remote Span in a `context.Context` using its SpanContext is unified to store just the current Span.
|
|
The Span's SpanContext can now self-identify as being remote or not.
|
|
This means that `"go.opentelemetry.io/otel/trace".ContextWithRemoteSpanContext` will now overwrite any existing current Span, not just existing remote Spans, and make it the current Span in a `context.Context`. (#1731)
|
|
- Improve OTLP/gRPC exporter connection errors. (#1737)
|
|
- Information about a parent span context in a `"go.opentelemetry.io/otel/export/trace".SpanSnapshot` is unified in a new `Parent` field.
|
|
The existing `ParentSpanID` and `HasRemoteParent` fields are removed in favor of this. (#1748)
|
|
- The `ParentContext` field of the `"go.opentelemetry.io/otel/sdk/trace".SamplingParameters` is updated to hold a `context.Context` containing the parent span.
|
|
This changes it to make `SamplingParameters` conform with the OpenTelemetry specification. (#1749)
|
|
- Updated Jaeger Environment Variables: `JAEGER_ENDPOINT`, `JAEGER_USER`, `JAEGER_PASSWORD`
|
|
to `OTEL_EXPORTER_JAEGER_ENDPOINT`, `OTEL_EXPORTER_JAEGER_USER`, `OTEL_EXPORTER_JAEGER_PASSWORD` in compliance with OTel specification. (#1752)
|
|
- Modify `BatchSpanProcessor.ForceFlush` to abort after timeout/cancellation. (#1757)
|
|
- The `DroppedAttributeCount` field of the `Span` in the `go.opentelemetry.io/otel` package now only represents the number of attributes dropped for the span itself.
|
|
It no longer is a conglomerate of itself, events, and link attributes that have been dropped. (#1771)
|
|
- Make `ExportSpans` in Jaeger Exporter honor context deadline. (#1773)
|
|
- Modify Zipkin Exporter default service name, use default resource's serviceName instead of empty. (#1777)
|
|
- The `go.opentelemetry.io/otel/sdk/export/trace` package is merged into the `go.opentelemetry.io/otel/sdk/trace` package. (#1778)
|
|
- The prometheus.InstallNewPipeline example is moved from comment to example test (#1796)
|
|
- The convenience functions for the stdout exporter have been updated to return the `TracerProvider` implementation and enable the shutdown of the exporter. (#1800)
|
|
- Replace the flush function returned from the Jaeger exporter's convenience creation functions (`InstallNewPipeline` and `NewExportPipeline`) with the `TracerProvider` implementation they create.
|
|
This enables the caller to shutdown and flush using the related `TracerProvider` methods. (#1822)
|
|
- Updated the Jaeger exporter to have a default endpoint, `http://localhost:14250`, for the collector. (#1824)
|
|
- Changed the function `WithCollectorEndpoint` in the Jaeger exporter to no longer accept an endpoint as an argument.
|
|
The endpoint can be passed with the `CollectorEndpointOption` using the `WithEndpoint` function or by setting the `OTEL_EXPORTER_JAEGER_ENDPOINT` environment variable value appropriately. (#1824)
|
|
- The Jaeger exporter no longer batches exported spans itself, instead it relies on the SDK's `BatchSpanProcessor` for this functionality. (#1830)
|
|
- The Jaeger exporter creation functions (`NewRawExporter`, `NewExportPipeline`, and `InstallNewPipeline`) no longer accept the removed `Option` type as a variadic argument. (#1830)
|
|
|
|
### Removed
|
|
|
|
- Removed Jaeger Environment variables: `JAEGER_SERVICE_NAME`, `JAEGER_DISABLED`, `JAEGER_TAGS`
|
|
These environment variables will no longer be used to override values of the Jaeger exporter (#1752)
|
|
- No longer set the links for a `Span` in `go.opentelemetry.io/otel/sdk/trace` that is configured to be a new root.
|
|
This is unspecified behavior that the OpenTelemetry community plans to standardize in the future.
|
|
To prevent backwards incompatible changes when it is specified, these links are removed. (#1726)
|
|
- Setting error status while recording error with Span from oteltest package. (#1729)
|
|
- The concept of a remote and local Span stored in a context is unified to just the current Span.
|
|
Because of this `"go.opentelemetry.io/otel/trace".RemoteSpanContextFromContext` is removed as it is no longer needed.
|
|
Instead, `"go.opentelemetry.io/otel/trace".SpanContextFromContex` can be used to return the current Span.
|
|
If needed, that Span's `SpanContext.IsRemote()` can then be used to determine if it is remote or not. (#1731)
|
|
- The `HasRemoteParent` field of the `"go.opentelemetry.io/otel/sdk/trace".SamplingParameters` is removed.
|
|
This field is redundant to the information returned from the `Remote` method of the `SpanContext` held in the `ParentContext` field. (#1749)
|
|
- The `trace.FlagsDebug` and `trace.FlagsDeferred` constants have been removed and will be localized to the B3 propagator. (#1770)
|
|
- Remove `Process` configuration, `WithProcessFromEnv` and `ProcessFromEnv`, and type from the Jaeger exporter package.
|
|
The information that could be configured in the `Process` struct should be configured in a `Resource` instead. (#1776, #1804)
|
|
- Remove the `WithDisabled` option from the Jaeger exporter.
|
|
To disable the exporter unregister it from the `TracerProvider` or use a no-operation `TracerProvider`. (#1806)
|
|
- Removed the functions `CollectorEndpointFromEnv` and `WithCollectorEndpointOptionFromEnv` from the Jaeger exporter.
|
|
These functions for retrieving specific environment variable values are redundant of other internal functions and
|
|
are not intended for end user use. (#1824)
|
|
- Removed the Jaeger exporter `WithSDKOptions` `Option`.
|
|
This option was used to set SDK options for the exporter creation convenience functions.
|
|
These functions are provided as a way to easily setup or install the exporter with what are deemed reasonable SDK settings for common use cases.
|
|
If the SDK needs to be configured differently, the `NewRawExporter` function and direct setup of the SDK with the desired settings should be used. (#1825)
|
|
- The `WithBufferMaxCount` and `WithBatchMaxCount` `Option`s from the Jaeger exporter are removed.
|
|
The exporter no longer batches exports, instead relying on the SDK's `BatchSpanProcessor` for this functionality. (#1830)
|
|
- The Jaeger exporter `Option` type is removed.
|
|
The type is no longer used by the exporter to configure anything.
|
|
All the previous configurations these options provided were duplicates of SDK configuration.
|
|
They have been removed in favor of using the SDK configuration and focuses the exporter configuration to be only about the endpoints it will send telemetry to. (#1830)
|
|
|
|

|
|
- Jaeger exporter populates Jaeger's Span Process from Resource. (#1673)

|
- Renamed the `LabelSet` method of `"go.opentelemetry.io/otel/sdk/resource".Resource` to `Set`. (#1692)
|
|
- Changed `WithSDK` to `WithSDKOptions` to accept variadic arguments of `TracerProviderOption` type in `go.opentelemetry.io/otel/exporters/trace/jaeger` package. (#1693)
|
|
- Changed `WithSDK` to `WithSDKOptions` to accept variadic arguments of `TracerProviderOption` type in `go.opentelemetry.io/otel/exporters/trace/zipkin` package. (#1693)
|
|

|
### Removed
|
|

|
|
- Removed `WithConfig` from tracer provider to avoid overriding configuration. (#1633)

|
|
- Removed setting status to `Error` while recording an error as a span event in `RecordError`. (#1663)

- Removed `jaeger.WithProcess` configuration option. (#1673)
|
|
- Removed `ApplyConfig` method from `"go.opentelemetry.io/otel/sdk/trace".TracerProvider` and the now unneeded `Config` struct. (#1693)

|
|
|
- Jaeger Exporter: Ensure mapping between OTEL and Jaeger span data complies with the specification. (#1626)

|
- The `otel-collector` example now correctly flushes metric events prior to shutting down the exporter. (#1678)
|
|
- Do not set span status message in `SpanStatusFromHTTPStatusCode` if it can be inferred from `http.status_code`. (#1681)
|
|
- Synchronization issues in global trace delegate implementation. (#1686)

|
|
They now are `Unset`, `Error`, and `Ok`.
|
|
They no longer track the gRPC codes. (#1214)
|
|
- The `StatusCode` field of the `SpanData` struct in the `go.opentelemetry.io/otel/sdk/export/trace` package now uses the codes package from this package instead of the gRPC project. (#1214)
|
|

|
|
|
- Add reconnecting udp connection type to Jaeger exporter.
|
|
This change adds a new optional implementation of the udp conn interface used to detect changes to an agent's host dns record.
|
|
It then adopts the new destination address to ensure the exporter doesn't get stuck. This change was ported from jaegertracing/jaeger-client-go#520. (#1063)
|
|
- Replace `StartOption` and `EndOption` in `go.opentelemetry.io/otel/api/trace` with `SpanOption`.
|

This change is matched by replacing the `StartConfig` and `EndConfig` with a unified `SpanConfig`. (#1108)
|
|
- Replace the `LinkedTo` span option in `go.opentelemetry.io/otel/api/trace` with `WithLinks`.
|
|
This is be more consistent with our other option patterns, i.e. passing the item to be configured directly instead of its component parts, and provides a cleaner function signature. (#1108)
|
|
- The `go.opentelemetry.io/otel/api/trace` `TracerOption` was changed to an interface to conform to project option conventions. (#1109)

This removal of the propagators is reflective of the OpenTelemetry specification for these propagators as well as cleans up the `go.opentelemetry.io/otel/api/trace` API. (#1118)
|
|
- Rename Jaeger tags used for instrumentation library information to reflect changes in OpenTelemetry specification. (#1119)
|
|

|
|
- Rename `ParentOrElse` sampler to `ParentBased` and allow setting samplers depending on parent span. (#1153)
|
|

|
|
recommend the use of `newConfig()` instead of `configure()`. (#1163)
|
|
- The `otlp.Config` type has been unexported and changed to `otlp.config`, along with its initializer. (#1163)
|
|
- Ensure exported interface types include parameter names and update the
|
|
Style Guide to reflect this styling rule. (#1172)
|
|
- Don't consider unset environment variable for resource detection to be an error. (#1170)
|
|
- Rename `go.opentelemetry.io/otel/api/metric.ConfigureInstrument` to `NewInstrumentConfig` and
|
|
`go.opentelemetry.io/otel/api/metric.ConfigureMeter` to `NewMeterConfig`.
|
|

- Change Metric Processor to merge multiple observations. (#1024)
|
|
- The `go.opentelemetry.io/otel/bridge/opentracing` bridge package has been made into its own module.
|
|
This removes the package dependencies of this bridge from the rest of the OpenTelemetry based project. (#1038)
|
|
- Renamed `go.opentelemetry.io/otel/api/standard` package to `go.opentelemetry.io/otel/semconv` to avoid the ambiguous and generic name `standard` and better describe the package as containing OpenTelemetry semantic conventions. (#1016)
|
|
- The environment variable used for resource detection has been changed from `OTEL_RESOURCE_LABELS` to `OTEL_RESOURCE_ATTRIBUTES` (#1042)
|
|
- Replace `WithSyncer` with `WithBatcher` in examples. (#1044)
|
|
- Replace the `google.golang.org/grpc/codes` dependency in the API with an equivalent `go.opentelemetry.io/otel/codes` package. (#1046)
|
|
- Merge the `go.opentelemetry.io/otel/api/label` and `go.opentelemetry.io/otel/api/kv` into the new `go.opentelemetry.io/otel/label` package. (#1060)
|
|
- Unify Callback Function Naming.
|
|
Rename `*Callback` with `*Func`. (#1061)
|
|
- CI builds validate against last two versions of Go, dropping 1.13 and adding 1.15. (#1064)
|
|
- The `go.opentelemetry.io/otel/sdk/export/trace` interfaces `SpanSyncer` and `SpanBatcher` have been replaced with a specification compliant `Exporter` interface.
|
|
This interface still supports the export of `SpanData`, but only as a slice.
|
|
Implementation are also required now to return any error from `ExportSpans` if one occurs as well as implement a `Shutdown` method for exporter clean-up. (#1078)
|
|
- The `go.opentelemetry.io/otel/sdk/trace` `NewBatchSpanProcessor` function no longer returns an error.
|
|
If a `nil` exporter is passed as an argument to this function, instead of it returning an error, it now returns a `BatchSpanProcessor` that handles the export of `SpanData` by not taking any action. (#1078)
|
|
- The `go.opentelemetry.io/otel/sdk/trace` `NewProvider` function to create a `Provider` no longer returns an error, instead only a `*Provider`.
|
|
This change is related to `NewBatchSpanProcessor` not returning an error which was the only error this function would return. (#1078)
|
|
|
|
### Removed
|
|
|
|
- Duplicate, unused API sampler interface. (#999)
|
|
Use the [`Sampler` interface](https://github.com/open-telemetry/opentelemetry-go/blob/v0.11.0/sdk/trace/sampling.go) provided by the SDK instead.
|
|
- The `grpctrace` instrumentation was moved to the `go.opentelemetry.io/contrib` repository and out of this repository.
|
|
This move includes moving the `grpc` example to the `go.opentelemetry.io/contrib` as well. (#1027)
|
|
- The `WithSpan` method of the `Tracer` interface.
|
|
The functionality this method provided was limited compared to what a user can provide themselves.
|
|
It was removed with the understanding that if there is sufficient user need it can be added back based on actual user usage. (#1043)
|
|
- The `RegisterSpanProcessor` and `UnregisterSpanProcessor` functions.
|
|
These were holdovers from an approach prior to the TracerProvider design. They were not used anymore. (#1077)
|
|
- The `oterror` package. (#1026)
|
|
- The `othttp` and `httptrace` instrumentations were moved to `go.opentelemetry.io/contrib`. (#1032)
|
|
|
|
### Fixed
|
|
|
|
- The `semconv.HTTPServerMetricAttributesFromHTTPRequest()` function no longer generates the high-cardinality `http.request.content.length` label. (#1031)
|
|
- Correct instrumentation version tag in Jaeger exporter. (#1037)
|
|
- The SDK span will now set an error event if the `End` method is called during a panic (i.e. it was deferred). (#1043)
|
|
- Move internally generated protobuf code from the `go.opentelemetry.io/otel` to the OTLP exporter to reduce dependency overhead. (#1050)
|
|
- The `otel-collector` example referenced outdated collector processors. (#1006)
|
|
|
|
## [0.10.0] - 2020-07-29
|
|
|
|
This release migrates the default OpenTelemetry SDK into its own Go module, decoupling the SDK from the API and reducing dependencies for instrumentation packages.
|
|
|
|
### Added
|
|
|
|
- The Zipkin exporter now has `NewExportPipeline` and `InstallNewPipeline` constructor functions to match the common pattern.
|
|
These function build a new exporter with default SDK options and register the exporter with the `global` package respectively. (#944)
|
|
- Add propagator option for gRPC instrumentation. (#986)
|
|
- The `testtrace` package now tracks the `trace.SpanKind` for each span. (#987)
|
|
|
|
### Changed
|
|
|
|
- Replace the `RegisterGlobal` `Option` in the Jaeger exporter with an `InstallNewPipeline` constructor function.
|
|
This matches the other exporter constructor patterns and will register a new exporter after building it with default configuration. (#944)
|
|
- The trace (`go.opentelemetry.io/otel/exporters/trace/stdout`) and metric (`go.opentelemetry.io/otel/exporters/metric/stdout`) `stdout` exporters are now merged into a single exporter at `go.opentelemetry.io/otel/exporters/stdout`.
|
|
This new exporter was made into its own Go module to follow the pattern of all exporters and decouple it from the `go.opentelemetry.io/otel` module. (#956, #963)
|
|
- Move the `go.opentelemetry.io/otel/exporters/test` test package to `go.opentelemetry.io/otel/sdk/export/metric/metrictest`. (#962)
|
|
- The `go.opentelemetry.io/otel/api/kv/value` package was merged into the parent `go.opentelemetry.io/otel/api/kv` package. (#968)
|
|
- `value.Bool` was replaced with `kv.BoolValue`.
|
|
- `value.Int64` was replaced with `kv.Int64Value`.
|
|
- `value.Uint64` was replaced with `kv.Uint64Value`.
|
|
- `value.Float64` was replaced with `kv.Float64Value`.
|
|
- `value.Int32` was replaced with `kv.Int32Value`.
|
|
- `value.Uint32` was replaced with `kv.Uint32Value`.
|
|
- `value.Float32` was replaced with `kv.Float32Value`.
|
|
- `value.String` was replaced with `kv.StringValue`.
|
|
- `value.Int` was replaced with `kv.IntValue`.
|
|
- `value.Uint` was replaced with `kv.UintValue`.
|
|
- `value.Array` was replaced with `kv.ArrayValue`.
|
|
- Rename `Infer` to `Any` in the `go.opentelemetry.io/otel/api/kv` package. (#972)
|
|
- Change `othttp` to use the `httpsnoop` package to wrap the `ResponseWriter` so that optional interfaces (`http.Hijacker`, `http.Flusher`, etc.) that are implemented by the original `ResponseWriter`are also implemented by the wrapped `ResponseWriter`. (#979)
|
|
- Rename `go.opentelemetry.io/otel/sdk/metric/aggregator/test` package to `go.opentelemetry.io/otel/sdk/metric/aggregator/aggregatortest`. (#980)
|
|
- Make the SDK into its own Go module called `go.opentelemetry.io/otel/sdk`. (#985)
|
|
- Changed the default trace `Sampler` from `AlwaysOn` to `ParentOrElse(AlwaysOn)`. (#989)
|
|
|
|
### Removed
|
|
|
|
- The `IndexedAttribute` function from the `go.opentelemetry.io/otel/api/label` package was removed in favor of `IndexedLabel` which it was synonymous with. (#970)
|
|
|
|
### Fixed
|
|
|
|
- Bump github.com/golangci/golangci-lint from 1.28.3 to 1.29.0 in /tools. (#953)
|
|
- Bump github.com/google/go-cmp from 0.5.0 to 0.5.1. (#957)
|
|
- Use `global.Handle` for span export errors in the OTLP exporter. (#946)
|
|
- Correct Go language formatting in the README documentation. (#961)
|
|
- Remove default SDK dependencies from the `go.opentelemetry.io/otel/api` package. (#977)
|
|
- Remove default SDK dependencies from the `go.opentelemetry.io/otel/instrumentation` package. (#983)
|
|
- Move documented examples for `go.opentelemetry.io/otel/instrumentation/grpctrace` interceptors into Go example tests. (#984)
|
|
|
|
## [0.9.0] - 2020-07-20
|
|
|
|
### Added
|
|
|
|
- A new Resource Detector interface is included to allow resources to be automatically detected and included. (#939)
|
|
- A Detector to automatically detect resources from an environment variable. (#939)
|
|
- Github action to generate protobuf Go bindings locally in `internal/opentelemetry-proto-gen`. (#938)
|
|
- OTLP .proto files from `open-telemetry/opentelemetry-proto` imported as a git submodule under `internal/opentelemetry-proto`.
|
|
References to `github.com/open-telemetry/opentelemetry-proto` changed to `go.opentelemetry.io/otel/internal/opentelemetry-proto-gen`. (#942)
|
|
|
|
### Changed
|
|
|
|
- Non-nil value `struct`s for key-value pairs will be marshalled using JSON rather than `Sprintf`. (#948)
|
|
|
|
### Removed
|
|
|
|
- Removed dependency on `github.com/open-telemetry/opentelemetry-collector`. (#943)
|
|
|
|
## [0.8.0] - 2020-07-09
|
|
|
|
### Added
|
|
|
|
- The `B3Encoding` type to represent the B3 encoding(s) the B3 propagator can inject.
|
|
A value for HTTP supported encodings (Multiple Header: `MultipleHeader`, Single Header: `SingleHeader`) are included. (#882)
|
|
- The `FlagsDeferred` trace flag to indicate if the trace sampling decision has been deferred. (#882)
|
|
- The `FlagsDebug` trace flag to indicate if the trace is a debug trace. (#882)
|
|
- Add `peer.service` semantic attribute. (#898)
|
|
- Add database-specific semantic attributes. (#899)
|
|
- Add semantic convention for `faas.coldstart` and `container.id`. (#909)
|
|
- Add http content size semantic conventions. (#905)
|
|
- Include `http.request_content_length` in HTTP request basic attributes. (#905)
|
|
- Add semantic conventions for operating system process resource attribute keys. (#919)
|
|
- The Jaeger exporter now has a `WithBatchMaxCount` option to specify the maximum number of spans sent in a batch. (#931)
|
|
|
|
### Changed
|
|
|
|
- Update `CONTRIBUTING.md` to ask for updates to `CHANGELOG.md` with each pull request. (#879)
|
|
- Use lowercase header names for B3 Multiple Headers. (#881)
|
|
- The B3 propagator `SingleHeader` field has been replaced with `InjectEncoding`.
|
|
This new field can be set to combinations of the `B3Encoding` bitmasks and will inject trace information in these encodings.
|
|
If no encoding is set, the propagator will default to `MultipleHeader` encoding. (#882)
|
|
- The B3 propagator now extracts from either HTTP encoding of B3 (Single Header or Multiple Header) based on what is contained in the header.
|
|
Preference is given to Single Header encoding with Multiple Header being the fallback if Single Header is not found or is invalid.
|
|
This behavior change is made to dynamically support all correctly encoded traces received instead of having to guess the expected encoding prior to receiving. (#882)
|
|
- Extend semantic conventions for RPC. (#900)
|
|
- To match constant naming conventions in the `api/standard` package, the `FaaS*` key names are appended with a suffix of `Key`. (#920)
|
|
- `"api/standard".FaaSName` -> `FaaSNameKey`
|
|
- `"api/standard".FaaSID` -> `FaaSIDKey`
|
|
- `"api/standard".FaaSVersion` -> `FaaSVersionKey`
|
|
- `"api/standard".FaaSInstance` -> `FaaSInstanceKey`
|
|
|
|
### Removed
|
|
|
|
- The `FlagsUnused` trace flag is removed.
|
|
The purpose of this flag was to act as the inverse of `FlagsSampled`, the inverse of `FlagsSampled` is used instead. (#882)
|
|
- The B3 header constants (`B3SingleHeader`, `B3DebugFlagHeader`, `B3TraceIDHeader`, `B3SpanIDHeader`, `B3SampledHeader`, `B3ParentSpanIDHeader`) are removed.
|
|
If B3 header keys are needed [the authoritative OpenZipkin package constants](https://pkg.go.dev/github.com/openzipkin/zipkin-go@v0.2.2/propagation/b3?tab=doc#pkg-constants) should be used instead. (#882)
|
|
|
|
### Fixed
|
|
|
|
- The B3 Single Header name is now correctly `b3` instead of the previous `X-B3`. (#881)
|
|
- The B3 propagator now correctly supports sampling only values (`b3: 0`, `b3: 1`, or `b3: d`) for a Single B3 Header. (#882)
|
|
- The B3 propagator now propagates the debug flag.
|
|
This removes the behavior of changing the debug flag into a set sampling bit.
|
|
Instead, this now follow the B3 specification and omits the `X-B3-Sampling` header. (#882)
|
|
- The B3 propagator now tracks "unset" sampling state (meaning "defer the decision") and does not set the `X-B3-Sampling` header when injecting. (#882)
|
|
- Bump github.com/itchyny/gojq from 0.10.3 to 0.10.4 in /tools. (#883)
|
|
- Bump github.com/opentracing/opentracing-go from v1.1.1-0.20190913142402-a7454ce5950e to v1.2.0. (#885)
|
|
- The tracing time conversion for OTLP spans is now correctly set to `UnixNano`. (#896)
|
|
- Ensure span status is not set to `Unknown` when no HTTP status code is provided as it is assumed to be `200 OK`. (#908)
|
|
- Ensure `httptrace.clientTracer` closes `http.headers` span. (#912)
|
|
- Prometheus exporter will not apply stale updates or forget inactive metrics. (#903)
|
|
- Add test for api.standard `HTTPClientAttributesFromHTTPRequest`. (#905)
|
|
- Bump github.com/golangci/golangci-lint from 1.27.0 to 1.28.1 in /tools. (#901, #913)
|
|
- Update otel-colector example to use the v0.5.0 collector. (#915)
|
|
- The `grpctrace` instrumentation uses a span name conforming to the OpenTelemetry semantic conventions (does not contain a leading slash (`/`)). (#922)
|
|
- The `grpctrace` instrumentation includes an `rpc.method` attribute now set to the gRPC method name. (#900, #922)
|
|
- The `grpctrace` instrumentation `rpc.service` attribute now contains the package name if one exists.
|
|
This is in accordance with OpenTelemetry semantic conventions. (#922)
|
|
- Correlation Context extractor will no longer insert an empty map into the returned context when no valid values are extracted. (#923)
|
|
- Bump google.golang.org/api from 0.28.0 to 0.29.0 in /exporters/trace/jaeger. (#925)
|
|
- Bump github.com/itchyny/gojq from 0.10.4 to 0.11.0 in /tools. (#926)
|
|
- Bump github.com/golangci/golangci-lint from 1.28.1 to 1.28.2 in /tools. (#930)
|
|
|
|
## [0.7.0] - 2020-06-26
|
|
|
|
This release implements the v0.5.0 version of the OpenTelemetry specification.
|
|
|
|
### Added
|
|
|
|
- The othttp instrumentation now includes default metrics. (#861)
|
|
- This CHANGELOG file to track all changes in the project going forward.
|
|
- Support for array type attributes. (#798)
|
|
- Apply transitive dependabot go.mod dependency updates as part of a new automatic Github workflow. (#844)
|
|
- Timestamps are now passed to exporters for each export. (#835)
|
|
- Add new `Accumulation` type to metric SDK to transport telemetry from `Accumulator`s to `Processor`s.
|
|
This replaces the prior `Record` `struct` use for this purpose. (#835)
|
|
- New dependabot integration to automate package upgrades. (#814)
|
|
- `Meter` and `Tracer` implementations accept instrumentation version version as an optional argument.
|
|
This instrumentation version is passed on to exporters. (#811) (#805) (#802)
|
|
- The OTLP exporter includes the instrumentation version in telemetry it exports. (#811)
|
|
- Environment variables for Jaeger exporter are supported. (#796)
|
|
- New `aggregation.Kind` in the export metric API. (#808)
|
|
- New example that uses OTLP and the collector. (#790)
|
|
- Handle errors in the span `SetName` during span initialization. (#791)
|
|
- Default service config to enable retries for retry-able failed requests in the OTLP exporter and an option to override this default. (#777)
|
|
- New `go.opentelemetry.io/otel/api/oterror` package to uniformly support error handling and definitions for the project. (#778)
|
|
- New `global` default implementation of the `go.opentelemetry.io/otel/api/oterror.Handler` interface to be used to handle errors prior to an user defined `Handler`.
|
|
There is also functionality for the user to register their `Handler` as well as a convenience function `Handle` to handle an error with this global `Handler`(#778)
|
|
- Options to specify propagators for httptrace and grpctrace instrumentation. (#784)
|
|
- The required `application/json` header for the Zipkin exporter is included in all exports. (#774)
|
|
- Integrate HTTP semantics helpers from the contrib repository into the `api/standard` package. #769
|
|
|
|
### Changed
|
|
|
|
- Rename `Integrator` to `Processor` in the metric SDK. (#863)
|
|
- Rename `AggregationSelector` to `AggregatorSelector`. (#859)
|
|
- Rename `SynchronizedCopy` to `SynchronizedMove`. (#858)
|
|
- Rename `simple` integrator to `basic` integrator. (#857)
|
|
- Merge otlp collector examples. (#841)
|
|
- Change the metric SDK to support cumulative, delta, and pass-through exporters directly.
|
|
With these changes, cumulative and delta specific exporters are able to request the correct kind of aggregation from the SDK. (#840)
|
|
- The `Aggregator.Checkpoint` API is renamed to `SynchronizedCopy` and adds an argument, a different `Aggregator` into which the copy is stored. (#812)
|
|
- The `export.Aggregator` contract is that `Update()` and `SynchronizedCopy()` are synchronized with each other.
|
|
All the aggregation interfaces (`Sum`, `LastValue`, ...) are not meant to be synchronized, as the caller is expected to synchronize aggregators at a higher level after the `Accumulator`.
|
|
Some of the `Aggregators` used unnecessary locking and that has been cleaned up. (#812)
|
|
- Use of `metric.Number` was replaced by `int64` now that we use `sync.Mutex` in the `MinMaxSumCount` and `Histogram` `Aggregators`. (#812)
|
|
- Replace `AlwaysParentSample` with `ParentSample(fallback)` to match the OpenTelemetry v0.5.0 specification. (#810)
|
|
- Rename `sdk/export/metric/aggregator` to `sdk/export/metric/aggregation`. #808
|
|
- Send configured headers with every request in the OTLP exporter, instead of just on connection creation. (#806)
|
|
- Update error handling for any one off error handlers, replacing, instead, with the `global.Handle` function. (#791)
|
|
- Rename `plugin` directory to `instrumentation` to match the OpenTelemetry specification. (#779)
|
|
- Makes the argument order to Histogram and DDSketch `New()` consistent. (#781)
|
|
|
|
### Removed
|
|
|
|
- `Uint64NumberKind` and related functions from the API. (#864)
|
|
- Context arguments from `Aggregator.Checkpoint` and `Integrator.Process` as they were unused. (#803)
|
|
- `SpanID` is no longer included in parameters for sampling decision to match the OpenTelemetry specification. (#775)
|
|
|
|
### Fixed

|
|
|
- Upgrade OTLP exporter to opentelemetry-proto matching the opentelemetry-collector v0.4.0 release. (#866)

## [0.3.0] - 2020-03-21
|
|
|
|
This is a first official beta release, which provides almost fully complete metrics, tracing, and context propagation functionality.
|
|
There is still a possibility of breaking changes.
|
|
|
|
### Added
|
|
|
|

|
|
- Add global `Propagators` functionality to enable deferred initialization for propagators registered before the first Meter SDK is installed. (#494)
|
|
- Simplified export setup pipeline for the jaeger exporter to match other exporters. (#459)
|
|

|
|
Additionally, `SyncImpl` and `AsyncImpl` are added to support general purpose instrument construction. (#560)
|
|
- A metric `Kind` is added to represent the `MeasureKind`, `ObserverKind`, and `CounterKind`. (#560)
|
|
- Scripts to better automate the release process. (#576)
|
|
|
|
### Changed
|
|
|
|
- Default to to use `AlwaysSampler` instead of `ProbabilitySampler` to match OpenTelemetry specification. (#506)
|
|
- Renamed `AlwaysSampleSampler` to `AlwaysOnSampler` in the trace API. (#511)
|
|
- Renamed `NeverSampleSampler` to `AlwaysOffSampler` in the trace API. (#511)
|
|
- The `Status` field of the `Span` was changed to `StatusCode` to disambiguate with the added `StatusMessage`. (#524)
|
|
- Updated the trace `Sampler` interface conform to the OpenTelemetry specification. (#531)
|
|
- Rename metric API `Options` to `Config`. (#541)
|
|
- Rename metric `Counter` aggregator to be `Sum`. (#541)
|
|

|
|
- Correct error in zipkin module name. (#548)
|
|
- The jaeger trace exporter now supports `Resource`s. (#551)
|
|
- Metric SDK now supports `Resource`s.
|
|
The `WithResource` option was added to configure a `Resource` on creation and the `Resource` method was added to the metric `Descriptor` to return the associated `Resource`. (#552)
|
|
- Replace `ErrNoLastValue` and `ErrEmptyDataSet` by `ErrNoData` in the metric SDK. (#557)
|
|
- The stdout trace exporter now supports `Resource`s. (#558)
|
|
- The metric `Descriptor` is now included at the API instead of the SDK. (#560)
|
|
- Replace `Ordered` with an iterator in `export.Labels`. (#567)
|
|
|
|
### Removed
|
|
|
|
- The vendor specific Stackdriver. It is now hosted on 3rd party vendor infrastructure. (#452)
|
|

|
|
- `GetDescriptor` from the metric SDK. (#575)
|
|
- The `Gauge` instrument from the metric API. (#537)
|
|
|
|
### Fixed
|
|
|
|
- Make histogram aggregator checkpoint consistent. (#438)
|
|
- Update README with import instructions and how to build and test. (#505)
|
|
- The default label encoding was updated to be unique. (#508)
|
|

|
|
- Fix data race in `BatchedSpanProcessor`. (#518)
|
|
- Skip test-386 for Mac OS 10.15.x (Catalina and upwards). #521
|
|
- Use a variable-size array to represent ordered labels in maps. (#523)

|
- Provide an implementation of the `Header*` filters that do not depend on Go 1.14. (#565)
|
|
- Encode labels once during checkpoint.
|
|
The checkpoint function is executed in a single thread so we can do the encoding lazily before passing the encoded version of labels to the exporter.
|
|
This is a cheap and quick way to avoid encoding the labels on every collection interval. (#572)
|
|
- Run coverage over all packages in `COVERAGE_MOD_DIR`. (#573)
|
|
|
|
## [0.2.3] - 2020-03-04
|
|
|
|
### Added
|
|
|
|
- `RecordError` method on `Span`s in the trace API to Simplify adding error events to spans. (#473)
|
|
- Configurable push frequency for exporters setup pipeline. (#504)
|
|
|
|
### Changed
|
|
|
|
- Rename the `exporter` directory to `exporters`.
|
|
The `go.opentelemetry.io/otel/exporter/trace/jaeger` package was mistakenly released with a `v1.0.0` tag instead of `v0.1.0`.
|
|
This resulted in all subsequent releases not becoming the default latest.
|
|
A consequence of this was that all `go get`s pulled in the incompatible `v0.1.0` release of that package when pulling in more recent packages from other otel packages.
|
|
Renaming the `exporter` directory to `exporters` fixes this issue by renaming the package and therefore clearing any existing dependency tags.
|
|
Consequentially, this action also renames *all* exporter packages. (#502)
|
|
|
|
### Removed
|
|
|
|
- The `CorrelationContextHeader` constant in the `correlation` package is no longer exported. (#503)
|
|

## [0.2.0] - 2019-12-03
|
|
|
|
### Added
|
|
|

|
|
- Prometheus exporter. (#334)
|
|
- Dogstatsd metrics exporter. (#326)
|
|
|
|
### Changed
|
|
|
|
- Rename `MaxSumCount` aggregation to `MinMaxSumCount` and add the `Min` interface for this aggregation. (#352)
|
|
- Rename `GetMeter` to `Meter`. (#357)
|
|
- Rename `HTTPTraceContextPropagator` to `TraceContextPropagator`. (#355)
|
|
- Rename `HTTPB3Propagator` to `B3Propagator`. (#355)

|
|
- Move `/global` package to `/api/global`. (#356)
|
|
- Rename `GetTracer` to `Tracer`. (#347)
|
|
|
|
### Removed
|
|
|
|
- `SetAttribute` from the `Span` interface in the trace API. (#361)
|
|
- `AddLink` from the `Span` interface in the trace API. (#349)
|
|
- `Link` from the `Span` interface in the trace API. (#349)
|
|
|
|
### Fixed
|
|
|
|
- Exclude example directories from coverage report. (#365)
|
|
- Lint make target now implements automatic fixes with `golangci-lint` before a second run to report the remaining issues. (#360)
|
|
- Drop `GO111MODULE` environment variable in Makefile as Go 1.13 is the project specified minimum version and this is environment variable is not needed for that version of Go. (#359)
|
|
- Run the race checker for all test. (#354)
|
|
- Redundant commands in the Makefile are removed. (#354)
|
|
- Split the `generate` and `lint` targets of the Makefile. (#354)
|
|
- Renames `circle-ci` target to more generic `ci` in Makefile. (#354)
|
|
- Add example Prometheus binary to gitignore. (#358)
|
|
- Support negative numbers with the `MaxSumCount`. (#335)
|
|
- Resolve race conditions in `push_test.go` identified in #339. (#340)
|
|
- Use `/usr/bin/env bash` as a shebang in scripts rather than `/bin/bash`. (#336)
|
|
- Trace benchmark now tests both `AlwaysSample` and `NeverSample`.
|
|
Previously it was testing `AlwaysSample` twice. (#325)
|
|
- Trace benchmark now uses a `[]byte` for `TraceID` to fix failing test. (#325)
|
|
- Added a trace benchmark to test variadic functions in `setAttribute` vs `setAttributes` (#325)
|
|
- The `defaultkeys` batcher was only using the encoded label set as its map key while building a checkpoint.
|
|
This allowed distinct label sets through, but any metrics sharing a label set could be overwritten or merged incorrectly.
|
|
This was corrected. (#333)
|
|
|
|
