See how to request a free trial license .* <img alt="vmgateway" src="vmgateway-overview.webp"> `vmgateway` is a proxy for the VictoriaMetrics Time Series Database (TSDB). It provides the following features: Rate Limiter Based on cluster tenant's utilization, it supports multiple time interval limits for both the ingestion and retrieval of metrics Token Access Control Supports additional per-label access control for both the Single and Cluster versions of the VictoriaMetrics TSDB Provides access by tenantID in the Cluster version Allows for separate write/read/admin access to data `vmgateway` is included in our . <img alt="vmgateway-ac" src="vmgateway-access-control.webp"> `vmgateway` supports jwt based authentication. With jwt payload can be configured to give access to specific tenants and labels as well as to 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" }, "extra_filters": ["{env=~\"prod|dev\",team!=\"test\"}"], "mode": 1 } } ``` Where: `exp` - required, expire time in unix_timestamp. If the token expires then `vmgateway` rejects the request. `vmaccess` - required, dict with claim info, minimum form: `{"vmaccess": {"tenant_id": {}}` `tenant_id` - optional, for cluster mode, routes requests to the corresponding tenant. `extralabels` - optional, key-value pairs for label filters added to the ingested or selected metrics. Multiple filters are added with `and` operation. If defined, `extralabel` from original request removed. `extrafilters` - optional, added to the select query requests. Multiple selectors are added with `or` operation. If defined, `extrafilter` from original request removed. `mode` - optional, access mode for api - read, write, or full. Supported values: 0 - full (default value), 1 - read, 2 - write. Start the single version of VictoriaMetrics ```sh ./bin/victoria-metrics --selfScrapeInterval=10s ``` Start vmgateway ```sh ./bin/vmgateway -eula -enable.auth -read.url http://localhost:8428 --write.url http://localhost:8428 ``` Retrieve data from the database ```sh curl 'http://localhost:8431/api/v1/series/count' -H 'Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ2bV9hY2Nlc3MiOnsidGVuYW50X2lkIjp7fSwicm9sZSI6MX0sImV4cCI6MTkzOTM0NjIxMH0.5WUxEfdcV9hKo4CtQdtuZYOGpGXWwaqM9VuVivMMrVg' ``` A request with an incorrect token or without any token will be rejected: ```sh curl 'http://localhost:8431/api/v1/series/count' curl 'http://localhost:8431/api/v1/series/count' -H 'Authorization: Bearer incorrect-token' ``` <img alt="vmgateway-rl" src="vmgateway-rate-limiting.webp"> Limits incoming requests by given, pre-configured limits. It supports read and write limiting by tenant. `vmgateway` needs a datasource for rate limit queries. It can be either single-node or cluster version of `victoria-metrics`. The metrics that you want to rate limit must be scraped from the cluster. List of supported limit types: `queries` - count of api requests made at tenant to read the api, such as `/api/v1/query`, `/api/v1/series` and others. `active_series` - count of current active series at any 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 a global level if you omit `projectid` and `accountid`. Example of configuration file: ```yaml limits: type: queries value: 1000 resolution: minute type: queries value: 10000 resolution: hour type: queries value: 10 resolution: minute project_id: 5 account_id: 1 ``` cluster version of VictoriaMetrics is required for rate limiting. ```sh cat << EOF > cluster.yaml scrape_configs: job_name: cluster scrape_interval: 5s static_configs: targets: ['127.0.0.1:8481','127.0.0.1:8482','127.0.0.1:8480'] EOF ./bin/victoria-metrics --promscrape.config cluster.yaml ./bin/vmstorage -eula ./bin/vmselect -eula -storageNode 127.0.0.1:8401 ./bin/vminsert -eula -storageNode 127.0.0.1:8400 cat << EOF >

Supported algorithms are `RS256`, `RS384`, `RS512`, `ES256`, `ES384`, `ES512`, `PS256`, `PS384`, `PS512`. Tokens with unsupported algorithms will be rejected. In order to enable JWT signature verification, you need to specify keys for signature verification. The following flags are used to specify keys: `-auth.publicKeyFiles` - allows to pass file path to file with public key. `-auth.publicKeys` - allows to pass public key directly. Note that both flags support passing multiple keys and also can be used together. Example usage: ```sh ./bin/vmgateway -eula \ -enable.auth \ -write.url=http://localhost:8480 \ -read.url=http://localhost:8481 \ -auth.publicKeyFiles=public_key.pem \ -auth.publicKeyFiles=public_key2.pem \ -auth.publicKeys=`--BEGIN PUBLIC KEY-- MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAu1SU1LfVLPHCozMxH2Mo 4lgOEePzNm0tRgeLezV6ffAt0gunVTLw7onLRnrq0/IzW7yWR7QkrmBL7jTKEn5u +qKhbwKfBstIs+bMY2Zkp18gnTxKLxoS2tFczGkPLPgizskuemMghRniWaoLcyeh kd3qqGElvW/VDL5AaWTg0nLVkjRo9z+40RQzuVaE8AkAFmxZzow3x+VJYKdjykkJ 0iT9wCS0DRTXu269V264Vf/3jvredZiKRkgwlL9xNAwxXFg0x/XFw005UWVRIkdg cKWTjpBP2dPwVZ4WWC+9aGVd+Gyn1o0CLelf4rEjGoXbAAEgAqeGUxrcIlbjXfbc mwIDAQAB --END PUBLIC KEY-- ` ``` This command will result in 3 keys loaded: 2 keys from files and 1 from command line. `vmgateway` supports using OpenID discovery endpoint for JWKS keys discovery. In order to enable endpoint for JWT signature verification, you need to specify OpenID discovery endpoint URLs by using `auth.oidcDiscoveryEndpoints` flag. When `auth.oidcDiscoveryEndpoints` is specified `vmageteway` will fetch JWKS keys from the specified endpoint and use them for JWT signature verification. Example usage for tokens issued by Azure Active Directory: ```sh /bin/vmgateway -eula \ -enable.auth \ -write.url=http://localhost:8480 \ -read.url=http://localhost:8481 \ -auth.oidcDiscoveryEndpoints=https://login.microsoftonline.com/common/v2.0/.well-known/openid-configuration ``` Example usage for tokens issued by Google: ```sh /bin/vmgateway -eula \ -enable.auth \ -write.url=http://localhost:8480 \ -read.url=http://localhost:8481 \ -auth.oidcDiscoveryEndpoints=https://accounts.google.com/.well-known/openid-configuration ``` `vmgateway` supports using JWKS endpoint for JWT signature verification. In order to enable JWKS endpoint for JWT signature verification, you need to specify JWKS endpoint URL by using `auth.jwksEndpoints` flag. When `auth.jwksEndpoints` is specified `vmageteway` will fetch public keys from the specified endpoint and use them for JWT signature verification. Example usage for tokens issued by Azure Active Directory: ```sh /bin/vmgateway -eula \ -enable.auth \ -write.url=http://localhost:8480 \ -read.url=http://localhost:8481 \ -auth.jwksEndpoints=https://login.microsoftonline.com/common/discovery/v2.0/keys ``` Example usage for tokens issued by Google: ```sh /bin/vmgateway -eula \ -enable.auth \ -write.url=http://localhost:8480 \ -read.url=http://localhost:8481 \ -auth.jwksEndpoints=https://www.googleapis.com/oauth2/v3/certs ``` Below is the list of configuration flags (it can be viewed by running `./vmgateway -help`): ```sh -auth.httpHeader string HTTP header name to look for JWT authorization token (default "Authorization") -auth.jwksEndpoints array JWKS endpoints to fetch keys for JWT tokens signature verification Supports an array of values separated by comma or specified via multiple flags.

(default 5m0s) -datasource.queryTimeAlignment Deprecated: please use "eval_alignment" in rule group instead. Whether to align "time" parameter with evaluation interval. Alignment supposed to produce deterministic results despite number of vmalert replicas or time they were started. See more details at https://github.com/VictoriaMetrics/VictoriaMetrics/pull/1257 (default true) -datasource.roundDigits int Adds "rounddigits" GET param to datasource requests. In VM "rounddigits" limits the number of digits after the decimal point in response values. -datasource.showURL Whether to avoid stripping sensitive information such as auth headers or passwords from URLs in log messages or UI and exported metrics.
