### enable (bool)

Enable collecting metrics data of the datarhei Core itself and the FFmpeg processes. The metrics can be queried via the [metrics API endpoint](/core/api/metrics.md).

By default collecting the metrics is disabled.

### enable\_prometheus (bool)

Enable prometheus endpoint at `/metrics`. This requires that collecting metrics is enabled.

By default this is disabled.

### range\_sec (integer)

Define for how many seconds historic metrics data should be kept.

By default this value is set to `300`.

### interval\_sec (integer)

Define in which interval (in seconds) the metrics should be collected.

By default this value is set to `2`.
