## Victori Metrics Gateway
|
||||
|
||||
|
||||
<img alt="vmgateway" src="vmgateway-overview.jpeg">
|
||||
|
||||
The service is a proxy for Victoria Metrics TSDB. It provides the next features:
|
||||
|
||||
* Rate Limiter
|
||||
* Based on cluster tenants' utilization supports multiple time interval limits for ingestion/retrieving metrics
|
||||
* Token Access Control
|
||||
* Supports additional per-label access control for Single and Cluster versions of Victoria Metrics TSDB
|
||||
* Provides access by tenantID at Cluster version
|
||||
* Allows to separate write/read/admin access to data
|
||||
|
||||
|
||||
### Access Control
|
||||
|
||||
<img alt="vmgateway-ac" src="vmgateway-access-control.jpg">
|
||||
|
||||
`vmgateway` supports jwt based authentication. With jwt payload can be configured access to specific tenant, labels, read/write.
|
||||
|
||||
jwt token must be in following format:
|
||||
```json
|
||||
{
|
||||
"exp": 1617304574,
|
||||
"vm_access": {
|
||||
"tenant_id": {
|
||||
"account_id": 1,
|
||||
"project_id": 5
|
||||
},
|
||||
"extra_labels": {
|
||||
"team": "dev",
|
||||
"project": "mobile"
|
||||
},
|
||||
"mode": 1
|
||||
}
|
||||
}
|
||||
```
|
||||
Where:
|
||||
- `exp` - required, expire time in unix_timestamp. If token expires, `vmgateway` rejects request.
|
||||
- `vm_access` - required, dict with claim info, minimum form: `{"vm_access": {"tenand_id": {}}`
|
||||
- `tenant_id` - optional, make sense only for cluster mode, routes request to corresponding tenant.
|
||||
- `extra_labels` - optional, key-value pairs for label filters - added to ingested or selected metrics.
|
||||
- `mode` - optional, access mode for api - read, write, full. supported values: 0 - full (default value), 1 - read, 2 - write.
|
||||
|
||||

### Rate Limiter
|
||||
|
||||
<img alt="vmgateway-rl" src="vmgateway-rate-limiting.jpg">
|
||||
|
||||
TODO: no information about source for rate limiting
|
||||
|
||||
Limits incoming requests by given pre-configured limits. It supports read and write limiting with `minute` and `hour` interval.
|
||||
|
||||
List of supported limit types:
|
||||
- `queries` - count of api requests made at tenant to read api, such as `/api/v1/query`, `/api/v1/series` and others.
|
||||
- `active_series` - count of current active series at given tenant.
|
||||
- `new_series` - count of created series aka churn rate
|
||||
- `rows_inserted` - count of inserted rows per tenant.
|
||||
|
||||
List of supported time windows:
|
||||
- `minute`
|
||||
- `hour`
|
||||
|
||||
Limits can be specified per tenant or at global level, if you omit `project_id` and `account_id`.
|
||||
|
||||
Example of configuration file:
|
||||
|
||||
```yaml
|
||||
limits:
|
||||
- type: queries
|
||||

```
|
||||
|
||||
### Configuration
|
||||
|
||||
The shortlist of configuration flags is the following:
|
||||
```bash
|
||||
-clusterMode
|
||||
enable it for cluster version
|
||||
-datasource.appendTypePrefix
|
||||
Whether to add type prefix to -datasource.url based on the query type. Set to true if sending different query types to VMSelect URL.
|
||||
-datasource.basicAuth.password string
|
||||
Optional basic auth password for -datasource.url
|
||||
-datasource.basicAuth.username string
|
||||
Optional basic auth username for -datasource.url
|
||||
-datasource.lookback duration
|
||||
Lookback defines how far to look into past when evaluating queries. For example, if datasource.lookback=5m then param "time" with value now()-5m will be added to every query.
|
||||
-datasource.maxIdleConnections int
|
||||
Defines the number of idle (keep-alive connections) to configured datasource.Consider to set this value equal to the value: groups_total * group.concurrency. Too low value may result into high number of sockets in TIME_WAIT state. (default 100)
|
||||
-datasource.queryStep duration
|
||||
queryStep defines how far a value can fallback to when evaluating queries. For example, if datasource.queryStep=15s then param "step" with value "15s" will be added to every query.
|
||||
-datasource.tlsCAFile string
|
||||
Optional path to TLS CA file to use for verifying connections to -datasource.url. By default system CA is used
|
||||

|
||||
Optional path to client-side TLS certificate key to use when connecting to -datasource.url
|
||||
-datasource.tlsServerName string
|
||||
Optional TLS server name to use for connections to -datasource.url. By default the server name from -datasource.url is used
|
||||
-datasource.url string
|
||||
Victoria Metrics or VMSelect url. Required parameter. E.g. http://127.0.0.1:8428
|
||||
-enable.auth
|
||||
enables auth with jwt token
|
||||
-enable.rateLimit
|
||||

|
||||
-enableTCP6
|
||||
Whether to enable IPv6 for listening and dialing. By default only IPv4 TCP and UDP is used
|
||||
-envflag.enable
|
||||
Whether to enable reading flags from environment variables additionally to command line. Command line flag values have priority over values from environment vars. Flags are read only from command line if this flag isnt set
|
||||
-envflag.prefix string
|
||||
Prefix for environment variables if -envflag.enable is set
|
||||
-eula
|
||||
By specifying this flag you confirm that you have an enterprise license and accept the EULA https://victoriametrics.com/assets/VM_EULA.pdf
|
||||
-fs.disableMmap
|
||||
Whether to use pread() instead of mmap() for reading data files. By default mmap() is used for 64-bit arches and pread() is used for 32-bit arches, since they cannot read data files bigger than 2^32 bytes in memory. mmap() is usually faster for reading small data chunks than pread()
|
||||
-http.connTimeout duration
|
||||
Incoming http connections are closed after the configured timeout. This may help spreading incoming load among a cluster of services behind load balancer. Note that the real timeout may be bigger by up to 10% as a protection from Thundering herd problem (default 2m0s)
|
||||
-http.disableResponseCompression
|
||||
Disable compression of HTTP responses for saving CPU resources. By default compression is enabled to save network bandwidth
|
||||
-http.idleConnTimeout duration
|
||||
Timeout for incoming idle http connections (default 1m0s)
|
||||
-http.maxGracefulShutdownDuration duration
|
||||
The maximum duration for graceful shutdown of HTTP server. Highly loaded server may require increased value for graceful shutdown (default 7s)
|
||||
-http.pathPrefix string
|
||||
An optional prefix to add to all the paths handled by http server. For example, if '-http.pathPrefix=/foo/bar' is set, then all the http requests will be handled on '/foo/bar/*' paths. This may be useful for proxied requests. See https://www.robustperception.io/using-external-urls-and-proxies-with-prometheus
|
||||
-http.shutdownDelay duration
|
||||
Optional delay before http server shutdown. During this dealy the servier returns non-OK responses from /health page, so load balancers can route new requests to other servers
|
||||
-httpAuth.password string
|
||||
Password for HTTP Basic Auth. The authentication is disabled if -httpAuth.username is empty
|
||||
-httpAuth.username string
|
||||
Username for HTTP Basic Auth. The authentication is disabled if empty. See also -httpAuth.password
|
||||
-httpListenAddr string
|
||||
TCP address to listen for http connections (default ":8431")
|
||||
-loggerDisableTimestamps
|
||||
Whether to disable writing timestamps in logs
|
||||
-loggerErrorsPerSecondLimit int
|
||||
Per-second limit on the number of ERROR messages. If more than the given number of errors are emitted per second, then the remaining errors are suppressed. Zero value disables the rate limit
|
||||
-loggerFormat string
|
||||
Format for logs. Possible values: default, json (default "default")
|
||||
-loggerLevel string
|
||||
Minimum level of errors to log. Possible values: INFO, WARN, ERROR, FATAL, PANIC (default "INFO")
|
||||
-loggerOutput string
|
||||
Output for the logs. Supported values: stderr, stdout (default "stderr")
|
||||
-loggerTimezone string
|
||||
Timezone to use for timestamps in logs. Timezone must be a valid IANA Time Zone. For example: America/New_York, Europe/Berlin, Etc/GMT+3 or Local (default "UTC")
|
||||
-loggerWarnsPerSecondLimit int
|
||||
Per-second limit on the number of WARN messages. If more than the given number of warns are emitted per second, then the remaining warns are suppressed. Zero value disables the rate limit
|
||||
-memory.allowedBytes size
|
||||
Allowed size of system memory VictoriaMetrics caches may occupy. This option overrides -memory.allowedPercent if set to non-zero value. Too low value may increase cache miss rate, which usually results in higher CPU and disk IO usage. Too high value may evict too much data from OS page cache, which will result in higher disk IO usage
|
||||
Supports the following optional suffixes for size values: KB, MB, GB, KiB, MiB, GiB (default 0)
|
||||
-memory.allowedPercent float
|
||||
Allowed percent of system memory VictoriaMetrics caches may occupy. See also -memory.allowedBytes. Too low value may increase cache miss rate, which usually results in higher CPU and disk IO usage. Too high value may evict too much data from OS page cache, which will result in higher disk IO usage (default 60)
|
||||
-metricsAuthKey string
|
||||
Auth key for /metrics. It overrides httpAuth settings
|
||||
-pprofAuthKey string
|
||||
Auth key for /debug/pprof. It overrides httpAuth settings
|
||||
-ratelimit.config string
|
||||
path for configuration file
|
||||
-ratelimit.extraLabels array
|
||||
additional labels, that will be applied to fetchdata from datasource
|
||||
Supports array of values separated by comma or specified via multiple flags.
|
||||
-ratelimit.refreshInterval duration
|
||||
(default 5s)
|
||||
-read.url string
|
||||
read access url address, example: http://vmselect:8481
|
||||
-tls
|
||||
Whether to enable TLS (aka HTTPS) for incoming requests. -tlsCertFile and -tlsKeyFile must be set if -tls is set
|
||||
-tlsCertFile string
|
||||
Path to file with TLS certificate. Used only if -tls is set. Prefer ECDSA certs instead of RSA certs, since RSA certs are slow
|
||||
-tlsKeyFile string
|
||||
Path to file with TLS key. Used only if -tls is set
|
||||
-version
|
||||
Show VictoriaMetrics version
|
||||
-write.url string
|
||||
write access url address, example: http://vminsert:8480
|
||||
|
||||
```
|
||||
|
||||
### TroubleShooting
|
||||
|
||||
* Access control:
|
||||
* incorrect `jwt` format, try https://jwt.io/#debugger-io with our tokens
|
||||
* expired token, check `exp` field.
|
||||
* Rate Limiting:
|
||||
* `scrape_interval` at datasource, reduce it to apply limits faster.
|
||||
|
||||
|
||||
### Limitations
|
||||
|
||||
* Access Control:
|
||||
* `jwt` token must be validated by external system, currently `vmauth` can't validate the signature.
|
||||
* RateLimiting:
|
||||
* limits applied based on queries to `datasource.url`

## Victori Metrics Gateway
|
||||
|
||||
|
||||
<img alt="vmgateway" src="vmgateway-overview.jpeg">
|
||||
|
||||
The service is a proxy for Victoria Metrics TSDB. It provides the next features:
|
||||
|
||||
* Rate Limiter
|
||||
* Based on cluster tenants' utilization supports multiple time interval limits for ingestion/retrieving metrics
|
||||
* Token Access Control
|
||||
* Supports additional per-label access control for Single and Cluster versions of Victoria Metrics TSDB
|
||||
* Provides access by tenantID at Cluster version
|
||||
* Allows to separate write/read/admin access to data
|
||||
|
||||
|
||||
### Access Control
|
||||
|
||||
<img alt="vmgateway-ac" src="vmgateway-access-control.jpg">
|
||||
|
||||
`vmgateway` supports jwt based authentication. With jwt payload can be configured access to specific tenant, labels, read/write.
|
||||
|
||||
jwt token must be in following format:
|
||||
```json
|
||||
{
|
||||
"exp": 1617304574,
|
||||
"vm_access": {
|
||||
"tenant_id": {
|
||||
"account_id": 1,
|
||||
"project_id": 5
|
||||
},
|
||||
"extra_labels": {
|
||||
"team": "dev",
|
||||
"project": "mobile"
|
||||
},
|
||||
"mode": 1
|
||||
}
|
||||
}
|
||||
```
|
||||
Where:
|
||||
- `exp` - required, expire time in unix_timestamp. If token expires, `vmgateway` rejects request.
|
||||
- `vm_access` - required, dict with claim info, minimum form: `{"vm_access": {"tenand_id": {}}`
|
||||
- `tenant_id` - optional, make sense only for cluster mode, routes request to corresponding tenant.
|
||||
- `extra_labels` - optional, key-value pairs for label filters - added to ingested or selected metrics.
|
||||
- `mode` - optional, access mode for api - read, write, full. supported values: 0 - full (default value), 1 - read, 2 - write.
|
||||
|
||||

|
||||
|
||||
TODO: no information about source for rate limiting
|
||||
|
||||
Limits incoming requests by given pre-configured limits. It supports read and write limiting with `minute` and `hour` interval.
|
||||
|
||||
List of supported limit types:
|
||||
- `queries` - count of api requests made at tenant to read api, such as `/api/v1/query`, `/api/v1/series` and others.
|
||||
- `active_series` - count of current active series at given tenant.
|
||||
- `new_series` - count of created series aka churn rate
|
||||
- `rows_inserted` - count of inserted rows per tenant.
|
||||
|
||||
List of supported time windows:
|
||||
- `minute`
|
||||
- `hour`
|
||||
|
||||
Limits can be specified per tenant or at global level, if you omit `project_id` and `account_id`.
|
||||
|
||||
Example of configuration file:
|
||||
|
||||
```yaml
|
||||

### Configuration
|
||||
|
||||
The shortlist of configuration flags is the following:
|
||||
```bash
|
||||
-clusterMode
|
||||
enable it for cluster version
|
||||
-datasource.appendTypePrefix
|
||||
Whether to add type prefix to -datasource.url based on the query type. Set to true if sending different query types to VMSelect URL.
|
||||
-datasource.basicAuth.password string
|
||||
Optional basic auth password for -datasource.url
|
||||
-datasource.basicAuth.username string
|
||||
Optional basic auth username for -datasource.url
|
||||
-datasource.lookback duration
|
||||
Lookback defines how far to look into past when evaluating queries. For example, if datasource.lookback=5m then param "time" with value now()-5m will be added to every query.
|
||||
-datasource.maxIdleConnections int
|
||||
Defines the number of idle (keep-alive connections) to configured datasource.Consider to set this value equal to the value: groups_total * group.concurrency. Too low value may result into high number of sockets in TIME_WAIT state. (default 100)
|
||||
-datasource.queryStep duration
|
||||
queryStep defines how far a value can fallback to when evaluating queries. For example, if datasource.queryStep=15s then param "step" with value "15s" will be added to every query.
|
||||
-datasource.tlsCAFile string
|
||||
Optional path to TLS CA file to use for verifying connections to -datasource.url. By default system CA is used
|
||||

|
||||
Optional path to client-side TLS certificate key to use when connecting to -datasource.url
|
||||
-datasource.tlsServerName string
|
||||
Optional TLS server name to use for connections to -datasource.url. By default the server name from -datasource.url is used
|
||||
-datasource.url string
|
||||
Victoria Metrics or VMSelect url. Required parameter. E.g. http://127.0.0.1:8428
|
||||
-enable.auth
|
||||
enables auth with jwt token
|
||||
-enable.rateLimit
|
||||

|
||||
-enableTCP6
|
||||
Whether to enable IPv6 for listening and dialing. By default only IPv4 TCP and UDP is used
|
||||
-envflag.enable
|
||||
Whether to enable reading flags from environment variables additionally to command line. Command line flag values have priority over values from environment vars. Flags are read only from command line if this flag isnt set
|
||||
-envflag.prefix string
|
||||
Prefix for environment variables if -envflag.enable is set
|
||||
-eula
|
||||
By specifying this flag you confirm that you have an enterprise license and accept the EULA https://victoriametrics.com/assets/VM_EULA.pdf
|
||||
-fs.disableMmap
|
||||
Whether to use pread() instead of mmap() for reading data files. By default mmap() is used for 64-bit arches and pread() is used for 32-bit arches, since they cannot read data files bigger than 2^32 bytes in memory. mmap() is usually faster for reading small data chunks than pread()
|
||||
-http.connTimeout duration
|
||||
Incoming http connections are closed after the configured timeout. This may help spreading incoming load among a cluster of services behind load balancer. Note that the real timeout may be bigger by up to 10% as a protection from Thundering herd problem (default 2m0s)
|
||||
-http.disableResponseCompression
|
||||
Disable compression of HTTP responses for saving CPU resources. By default compression is enabled to save network bandwidth
|
||||
-http.idleConnTimeout duration
|
||||
Timeout for incoming idle http connections (default 1m0s)
|
||||
-http.maxGracefulShutdownDuration duration
|
||||
The maximum duration for graceful shutdown of HTTP server. Highly loaded server may require increased value for graceful shutdown (default 7s)
|
||||
-http.pathPrefix string
|
||||
An optional prefix to add to all the paths handled by http server. For example, if '-http.pathPrefix=/foo/bar' is set, then all the http requests will be handled on '/foo/bar/*' paths. This may be useful for proxied requests. See https://www.robustperception.io/using-external-urls-and-proxies-with-prometheus
|
||||
-http.shutdownDelay duration
|
||||
Optional delay before http server shutdown. During this dealy the servier returns non-OK responses from /health page, so load balancers can route new requests to other servers
|
||||
-httpAuth.password string
|
||||
Password for HTTP Basic Auth. The authentication is disabled if -httpAuth.username is empty
|
||||
-httpAuth.username string
|
||||
Username for HTTP Basic Auth. The authentication is disabled if empty. See also -httpAuth.password
|
||||
-httpListenAddr string
|
||||

|
||||
-loggerDisableTimestamps
|
||||
Whether to disable writing timestamps in logs
|
||||
-loggerErrorsPerSecondLimit int
|
||||
Per-second limit on the number of ERROR messages. If more than the given number of errors are emitted per second, then the remaining errors are suppressed. Zero value disables the rate limit
|
||||
-loggerFormat string
|
||||
Format for logs. Possible values: default, json (default "default")
|
||||
-loggerLevel string
|
||||
Minimum level of errors to log. Possible values: INFO, WARN, ERROR, FATAL, PANIC (default "INFO")

|
||||
-loggerWarnsPerSecondLimit int
|
||||
Per-second limit on the number of WARN messages. If more than the given number of warns are emitted per second, then the remaining warns are suppressed. Zero value disables the rate limit
|
||||
-memory.allowedBytes size
|
||||
Allowed size of system memory VictoriaMetrics caches may occupy. This option overrides -memory.allowedPercent if set to non-zero value. Too low value may increase cache miss rate, which usually results in higher CPU and disk IO usage. Too high value may evict too much data from OS page cache, which will result in higher disk IO usage
|
||||
Supports the following optional suffixes for size values: KB, MB, GB, KiB, MiB, GiB (default 0)
|
||||
-memory.allowedPercent float
|
||||
Allowed percent of system memory VictoriaMetrics caches may occupy. See also -memory.allowedBytes. Too low value may increase cache miss rate, which usually results in higher CPU and disk IO usage. Too high value may evict too much data from OS page cache, which will result in higher disk IO usage (default 60)
|
||||
-metricsAuthKey string
|
||||
Auth key for /metrics. It overrides httpAuth settings
|
||||
-pprofAuthKey string
|
||||
Auth key for /debug/pprof. It overrides httpAuth settings
|
||||
-ratelimit.config string
|
||||
path for configuration file
|
||||
-ratelimit.extraLabels array
|
||||
additional labels, that will be applied to fetchdata from datasource
|
||||
Supports array of values separated by comma or specified via multiple flags.
|
||||
-ratelimit.refreshInterval duration
|
||||
(default 5s)
|
||||
-read.url string
|
||||
read access url address, example: http://vmselect:8481
|
||||
-tls
|
||||
Whether to enable TLS (aka HTTPS) for incoming requests. -tlsCertFile and -tlsKeyFile must be set if -tls is set
|
||||
-tlsCertFile string
|
||||
Path to file with TLS certificate. Used only if -tls is set. Prefer ECDSA certs instead of RSA certs, since RSA certs are slow
|
||||
-tlsKeyFile string
|
||||
Path to file with TLS key. Used only if -tls is set
|
||||
-version
|
||||
Show VictoriaMetrics version
|
||||
-write.url string
|
||||
write access url address, example: http://vminsert:8480
|
||||
|
||||
```
|
||||
|
||||
### TroubleShooting
|
||||
|
||||
* Access control:
|
||||
* incorrect `jwt` format, try https://jwt.io/#debugger-io with our tokens
|
||||
* expired token, check `exp` field.
|
||||
* Rate Limiting:
|
||||
* `scrape_interval` at datasource, reduce it to apply limits faster.
|
||||
|
||||
|
||||
### Limitations
|
||||
|
||||
* Access Control:
|
||||
* `jwt` token must be validated by external system, currently `vmauth` can't validate the signature.
|
||||
* RateLimiting:
|
||||
* limits applied based on queries to `datasource.url`
