***vmgateway is a part of [enterprise package](https://docs.victoriametrics.com/enterprise/).
It is available for download and evaluation at [releases page](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/latest).
See how to request a free trial license [here](https://victoriametrics.com/products/enterprise/trial/).***
![vmgateway](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 [enterprise packages](https://docs.victoriametrics.com/enterprise/).
## Access Control
![vmgateway-ac](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 one of the following formats:
with `vm_access` claim as JSON object
```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
}
}
```
or with `vm_access` claim as string
```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.
* `vm_access` - required, dict with claim info, minimum form: `{"vm_access": {"tenant_id": {}}`
* `tenant_id` - optional, for cluster mode, routes requests to the corresponding tenant.
* `extra_labels` - optional, key-value pairs for label filters added to the ingested or selected metrics. Multiple filters are added with `and` operation. If defined, `extra_label` from original request removed.
* `extra_filters` - optional, [series selectors](https://prometheus.io/docs/prometheus/latest/querying/basics/#time-series-selectors) added to the select query requests. Multiple selectors are added with `or` operation. If defined, `extra_filter` from original request removed.
* `mode` - optional, access mode for api - read, write, or full. Supported values: 0 - full (default value), 1 - read, 2 - write.
## QuickStart
Start the single version of VictoriaMetrics
```sh
# single
# start node
./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'
```
## Rate Limiter
![vmgateway-rl](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 `project_id` and `account_id`.
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
```
## QuickStart
cluster version of VictoriaMetrics is required for rate limiting.
```sh
# start datasource for cluster metrics
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
# start cluster
# start vmstorage, vmselect and vminsert
./bin/vmstorage -eula
./bin/vmselect -eula -storageNode 127.0.0.1:8401
./bin/vminsert -eula -storageNode 127.0.0.1:8400
# create base rate limiting config:
cat << EOF > limit.yaml
limits:
- type: queries
value: 100
- type: rows_inserted
value: 100000
- type: new_series
value: 1000
- type: active_series
value: 100000

## JWT signature verification
`vmgateway` supports JWT signature verification.
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-----

-----END PUBLIC KEY-----
`
```
This command will result in 3 keys loaded: 2 keys from files and 1 from command line.
### Using OpenID discovery endpoint for JWT signature verification
`vmgateway` supports using OpenID discovery endpoint for JWKS keys discovery.
In order to enable [OpenID discovery](https://openid.net/specs/openid-connect-discovery-1_0.html) endpoint for JWT signature verification, you need to specify OpenID discovery endpoint URLs by using `auth.oidcDiscoveryEndpoints` flag.
When `auth.oidcDiscoveryEndpoints` is specified `vmgateway` 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
```
### Using JWKS endpoint for JWT signature verification
`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 `vmgateway` 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
```

-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 delay, the server returns non-OK responses from /health page, so load balancers can route new requests to other servers

-remoteRead.disablePathAppend
Whether to disable automatic appending of '/api/v1/query' path to the configured -datasource.url and -remoteRead.url
-tls array
Whether to enable TLS for incoming HTTP requests at the given -httpListenAddr (aka https). -tlsCertFile and -tlsKeyFile must be set if -tls is set. See also -mtls
Supports array of values separated by comma or specified via multiple flags.
Empty values are set to false.
-tlsAutocertCacheDir string
Directory to store TLS certificates issued via Let's Encrypt. Certificates are lost on restarts if this flag isn't set. This flag is available only in Enterprise binaries. See https://docs.victoriametrics.com/enterprise/
-tlsAutocertEmail string
Contact email for the issued Let's Encrypt TLS certificates. See also -tlsAutocertHosts and -tlsAutocertCacheDir .This flag is available only in Enterprise binaries. See https://docs.victoriametrics.com/enterprise/
-tlsAutocertHosts array
Optional hostnames for automatic issuing of Let's Encrypt TLS certificates. These hostnames must be reachable at -httpListenAddr . The -httpListenAddr must listen tcp port 443 . The -tlsAutocertHosts overrides -tlsCertFile and -tlsKeyFile . See also -tlsAutocertEmail and -tlsAutocertCacheDir . This flag is available only in Enterprise binaries. See https://docs.victoriametrics.com/enterprise/
Supports an array of values separated by comma or specified via multiple flags.
Value can contain comma inside single-quoted or double-quoted string, {}, [] and () braces.
-tlsCertFile array
Path to file with TLS certificate for the corresponding -httpListenAddr if -tls is set. Prefer ECDSA certs instead of RSA certs as RSA certs are slower. The provided certificate file is automatically re-read every second, so it can be dynamically updated. See also -tlsAutocertHosts
Supports an array of values separated by comma or specified via multiple flags.
Value can contain comma inside single-quoted or double-quoted string, {}, [] and () braces.
-tlsCipherSuites array
Optional list of TLS cipher suites for incoming requests over HTTPS if -tls is set. See the list of supported cipher suites at https://pkg.go.dev/crypto/tls#pkg-constants
Supports an array of values separated by comma or specified via multiple flags.
Value can contain comma inside single-quoted or double-quoted string, {}, [] and () braces.
-tlsKeyFile array
Path to file with TLS key for the corresponding -httpListenAddr if -tls is set. The provided key file is automatically re-read every second, so it can be dynamically updated. See also -tlsAutocertHosts
Supports an array of values separated by comma or specified via multiple flags.
Value can contain comma inside single-quoted or double-quoted string, {}, [] and () braces.
-tlsMinVersion array
Optional minimum TLS version to use for the corresponding -httpListenAddr if -tls is set. Supported values: TLS10, TLS11, TLS12, TLS13
Supports an array of values separated by comma or specified via multiple flags.
Value can contain comma inside single-quoted or double-quoted string, {}, [] and () braces.
-version

## 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 signature verification for `HMAC` algorithms is not supported.
* RateLimiting:
* limits applied based on queries to `datasource.url`
* only cluster version can be rate-limited.
