It was calculating the number of dropped time series instead of the number of dropped samples.
While at it, drop vmalert_remotewrite_dropped_bytes_total metric, since it was inconsistently calculated -
at one place it was calculating raw protobuf-encoded sample sizes, while at another place it was calculating
the size of snappy-compressed prompbmarshal.WriteRequest protobuf message.
Additionally, this metric has zero practical sense, so just drop it in order to reduce the level of confusion.

Some clients may ingest samples via OpenTelemetry protocol without Resource labels.
Previously VictoriaMetrics was silently dropping such samples.
The commit 317834f876 added vm_protoparser_rows_dropped_total{type="opentelemetry",reason="resource_not_set"}
counter for tracking of such dropped samples. See https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5459
It is better from usability PoV to accept such samples instead of dropping them and incrementing the corresponding counter.
Before, retries happened only on writes into a network connection
between source and destination. But errors returned by server after
all the data was transmitted were logged, but not retried.

Previously concurrency for static and fast queries was limited with the -search.maxConcurrentRequests

since `vmui` and these pages couldn't be opened on overloaded vmselect.
Thanks to @f41gh7 for the idea.

This should improve debuging why particular targets are dropped.
While at it, do not remove dropped targets from the list at /service-discovery page
until the total number of targets exceeds the limit passed to -promscrape.maxDroppedTargets .

* app/vmagent: allow to disabled on-disk queue
Previously, it wasn't possible to build data processing pipeline with a
chain of vmagents. In case when remoteWrite for the last vmagent in the
chain wasn't accessible, it persisted data only when it has enough disk
capacity. If disk queue is full, it started to silently drop ingested
metrics.
New flags allows to disable on-disk persistent and immediatly return an
error if remoteWrite is not accessible anymore. It blocks any writes and
notify client, that data ingestion isn't possible.
Main use case for this feature - use external queue such as kafka for
data persistence.

In the scenario when user exports and imports data from one VM to another,
it could possibly lead to OOM exception for destination VM.

This case is possible after the following steps:
1. vmagent successfully performed handshake with the -remoteWrite.url and the remote storage supports zstd-compressed data.
2. remote storage became unavailable or slow to ingest data, vmagent compressed the collected data into blocks with zstd and puts these blocks to persistent queue on disk.
3. vmagent restarts and the remote storage is unavailable during the handshake, then vmagent falls back to Snappy compression.
4. vmagent starts sending zstd-compressed data from persistent queue to the remote storage, while falsely advertizing it sends Snappy-compressed data.
5. The remote storage receives zstd-compressed data and fails unpacking it with Snappy.
The solution is the same as 12cd32fd75, just fall back to zstd decompression if Snappy decompression fails.

deadline during reading or writing to an internal buffer.
With this change, buffered connection struct additionally checks

evalRollupFuncNoCache() may return time series with identical labels (aka duplicate series)
when performing queries satisfying all the following conditions:
- It must select time series with multiple metric names. For example, {__name__=~"foo|bar"}
- The series selector must be wrapped into rollup function, which drops metric names. For example, rate({__name__=~"foo|bar"})
- The rollup function must be wrapped into aggregate function, which has no streaming optimization.
For example, quantile(0.9, rate({__name__=~"foo|bar"})
In this case VictoriaMetrics shouldn't return `cannot merge series: duplicate series found` error.
Instead, it should fall back to query execution with disabled cache.

Repeated instant queries with long lookbehind windows, which contain one of the following rollup functions,
are optimized via partial result caching:
- sum_over_time()
- count_over_time()
- avg_over_time()
- increase()
- rate()
The basic idea of optimization is to calculate
rf(m[d] @ t)
as
rf(m[offset] @ t) + rf(m[d] @ (t-offset)) - rf(m[offset] @ (t-d))
where rf(m[d] @ (t-offset)) is cached query result, which was calculated previously
The offset may be in the range of up to 1 hour.

- Make sure that invalid/missing TLS CA file or TLS client certificate files at vmagent startup
don't prevent from processing the corresponding scrape targets after the file becomes correct,
without the need to restart vmagent.
Previously scrape targets with invalid TLS CA file or TLS client certificate files
were permanently dropped after the first attempt to initialize them, and they didn't
appear until the next vmagent reload or the next change in other places of the loaded scrape configs.
- Make sure that TLS CA is properly re-loaded from file after it changes without the need to restart vmagent.
Previously the old TLS CA was used until vmagent restart.
- Properly handle errors during http request creation for the second attempt to send data to remote system
at vmagent and vmalert. Previously failed request creation could result in nil pointer dereferencing,
since the returned request is nil on error.
- Add more context to the logged error during AWS sigv4 request signing before sending the data to -remoteWrite.url at vmagent.
Previously it could miss details on the source of the request.
- Do not create a new HTTP client per second when generating OAuth2 token needed to put in Authorization header
of every http request issued by vmagent during service discovery or target scraping.
Re-use the HTTP client instead until the corresponding scrape config changes.
- Cache error at lib/promauth.Config.GetAuthHeader() in the same way as the auth header is cached,
e.g. the error is cached for a second now. This should reduce load on CPU and OAuth2 server
when auth header cannot be obtained because of temporary error.
- Share tls.Config.GetClientCertificate function among multiple scrape targets with the same tls_config.
Cache the loaded certificate and the error for one second. This should significantly reduce CPU load
when scraping big number of targets with the same tls_config.
- Allow loading TLS certificates from HTTP and HTTPs urls by specifying these urls at `tls_config->cert_file` and `tls_config->key_file`.
- Improve test coverage at lib/promauth
- Skip unreachable or invalid files specified at `scrape_config_files` during vmagent startup, since these files may become valid later.
Previously vmagent was exitting in this case.

re-phrasing and linking missing docs.
`eval_delay` was added to tests to verify it can be unmarshalled.
`eval_delay` is now applied before timestamp alignment to make it more predictable.
Before, if delay < interval the timestamp won't be aligned.
`eval_delay` and `eval_offset` was added to API output.
`PreviouslySentSeriesToRW` converted to private `previouslySentSeriesToRW`.

This can be useful in the following queries:
drop_empty_series(temperature <= 30) default 40
This query drops temperature series with all the values bigger than 30 on the selected time range,
while replacing gaps in the remaining series with 40.
The query without drop_empty_series:
(temperature <= 30) default 40
would leave all the temperature series with all the values bigger than 30 on the selected time range,
and replace all their values with 40. This is not what could be epxected in some cases

This is a follow-up for f60c08a7bd
Changes:
- Make sure all the urls related to NewRelic protocol start from /newrelic . Previously some urls were started from /api/v1/newrelic
- Remove /api/v1 part from NewRelic urls, since it has no sense
- Remove automatic transformation from CamelCase to snake_case for NewRelic labels and metric names,
since it may complicate the transition from NewRelic to VictoriaMetrics. Preserve all the metric names and label names,
so users could query metrics and labels by the same names which are used in NewRelic.
The automatic transformation from CamelCase to snake_case can be added later as a special action for relabeling rules if needed.
- Properly update per-tenant data ingestion stats at app/vmagent/newrelic/request_handler.go . Previously it was always zero.
- Fix NewRelic urls in vmagent when multitenant data ingestion is enabled. Previously they were mistakenly started from `/`.
- Document NewRelic data ingestion url at docs/Cluster-VictoriaMetrics.md
- Remove superflouos memory allocations at lib/protoparser/newrelic
- Improve tests at lib/protoparser/newrelic/*
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3520
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/pull/4712
- Make more clear the docs at docs/enterprise.md, so readers could figure out faster
on how to obtain enterprise key and how to pass it to VictoriaMetrics Enterprise components.
- Fix examples at docs/enterprise.md, which were referring to non-existing `-license-file` command-line flag.
The `-licenseFile` command-line flag must be used instead.
- Improve the description of `-license*` command-line flags, so users could understand
faster how to use them.
- Improve the warning message, which is emitted when the deprecated -eula command-line flag is passed,
so the user could figure out how to switch faster to -license* command-line flags.
- Disallow running VictoriaMetrics components with both -license and -licenseFile command-line flags.
- Disallow running VictoriaMetrics components when -licensFile points to an empty file.
- Consistently use the phrase "This flag is available only in Enterprise binaries" across
all the enterprise-specific command-line flags.
- Remove unneeded level of indirection for `noLicenseMessage` and `expiredMessage` string contants
in order to improve code readability and maintainability.
- Remove unneded `return` statements after `logger.Fatalf()` calls, since these calls exit the app and never return.
- Make sure that the info log message about successful license verification is emitted
when the license is verified successfully. Previously the error message could be logged
when the license payload is invalid or if it misses some required features.
- Reduce vertical space usage, so more information is available on the screen without the need to scroll.
- Show information for lines with higher values at the top of the legend under the graph.
This should simplify graph analysis when it contains many lines.
Fix vminsert/vmstorage/vmselect metrics filtering when dashboard is used

* lib/promscrape: make concurrency control optional
Before, `-maxConcurrentInserts` was limiting all calls to `promscrape.Parse`
function: during ingestion and scraping. This behavior is incorrect.
Cmd-line flag `-maxConcurrentInserts` should have effect onl on ingestion.
Since both pipelines use the same `promscrape.Parse` function, we extend it
to make concurrency limiter optional. So caller can decide whether concurrency
should be limited or not.

- Move uniqueFields from rows to blockStreamMerger struct.
This allows localizing all the references to uniqueFields inside blockStreamMerger.mustWriteBlock(),
which should improve readability and maintainability of the code.
- Remove logging of the event when blocks cannot be merged because they contain more than maxColumnsPerBlock,
since the provided logging didn't provide the solution for the issue with too many columns.
I couldn't figure out the proper solution, which could be helpful for end user,
so decided to remove the logging until we find the solution.
This commit also contains the following additional changes:
- It truncates field names longer than 128 chars during logs ingestion.
This should prevent from ingesting bogus field names.
This also should prevent from too big columnsHeader blocks,
which could negatively affect search query performance,
since columnsHeader is read on every scan of the corresponding data block.
- It limits the maximum length of const column value to 256.
Longer values are stored in an ordinary columns.
This helps limiting the size of columnsHeader blocks
and improving search query performance by avoiding
reading too long const columns on every scan of the corresponding data block.
- It deduplicates columns with identical names during data ingestion
and background merging. Previously it was possible to pass columns with duplicate names
to block.mustInitFromRows(), and they were stored as is in the block.

Initially, stream parse mode was reading data from response and parsing it on flight. This was causing longer delay to read the whole response and required increasing timeout value to allow data processing while reading. So that 908e35affd increased timeout value to fix this.
But after 74c00a8762 response in stream parse mode is saved into memory and then parsed eliminating necessity of having timeout value higher that for usual scrape.

The `ConcurrentFlushesHitTheLimit` could be related to components like
vminsert, vmstorage, vm-single-node and vmagent. Moving this alert
to the `health` section of alerts will be benefitial for all components
and will remove the duplicates from single/cluster alerts.

Binary export API protocol can be disabled via `-vm-native-disable-binary-protocol` cmd-line flag when migrating data from VictoriaMetrics. Disabling binary protocol
can be useful for deduplication of the exported data before ingestion.
For this, deduplication need to be configured at `-vm-native-src-addr` side
and `-vm-native-disable-binary-protocol` should be set on vmctl side.
