# Metrics

Traefik supports these metrics backends:

- [Datadog](./datadog.md)
- [InfluxDB2](./influxdb2.md)
- [Prometheus](./prometheus.md)
- [StatsD](./statsd.md)

Traefik Proxy hosts an official Grafana dashboard for both [on-premises](https://grafana.com/grafana/dashboards/17346) and [Kubernetes](https://grafana.com/grafana/dashboards/17347) deployments.

!!! info "`method` label value"

    If the HTTP method verb on a request is not one defined in the set of common methods for [`HTTP/1.1`](https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods)
    or the [`PRI`](https://datatracker.ietf.org/doc/html/rfc7540#section-11.6) verb (for `HTTP/2`),
    then the value for the method label becomes `EXTENSION_METHOD`.
