title: "Traefik Metrics Overview"
description: "Traefik Proxy supports these metrics backend systems: Datadog, InfluxDB 2.X, Prometheus, and StatsD. Read the full documentation to get started."

# Metrics
Traefik provides metrics in the [OpenTelemetry](./opentelemetry.md) format as well as the following vendor specific 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.
## Common Options
### `addInternals`
_Optional, Default="false"_
Enables metrics for internal resources (e.g.: `ping@internals`).
```yaml tab="File (YAML)"
metrics:
addInternals: true
```
```toml tab="File (TOML)"
[metrics]
addInternals = true
```
```bash tab="CLI"
--metrics.addinternals
```
## Global Metrics

!!! 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`.
