+The configuration supports three kind of metrics from the [OpenMetrics specification](https://github.com/prometheus/OpenMetrics/blob/v1.0.0/specification/OpenMetrics.md).
 
 The metric type is specified by the `type` field and its specific configuration at the types specific struct.

Common examples are an application's version, revision control commit, and the version of a compiler.
