# Prometheus

Woodpecker is compatible with Prometheus and exposes a `/metrics` endpoint if the environment variable `WOODPECKER_PROMETHEUS_AUTH_TOKEN` is set. Please note that access to the metrics endpoint is restricted and requires the authorization token from the environment variable mentioned above.

```yaml
global:
  scrape_interval: 60s

scrape_configs:
  - job_name: 'woodpecker'
    bearer_token: dummyToken...

    static_configs:
      - targets: ['woodpecker.domain.com']
```

## Authorization

An administrator will need to generate a user API token and configure in the Prometheus configuration file as a bearer token. Please see the following example:

```diff
 global:
   scrape_interval: 60s

 scrape_configs:
   - job_name: 'woodpecker'
+    bearer_token: dummyToken...

     static_configs:
        - targets: ['woodpecker.domain.com']
```

As an alternative, the token can also be read from a file:

```diff
 global:
   scrape_interval: 60s

 scrape_configs:
   - job_name: 'woodpecker'
+    bearer_token_file: /etc/secrets/woodpecker-monitoring-token

     static_configs:
        - targets: ['woodpecker.domain.com']
```
