-The configuration supports three kind of metrics from the [OpenMetrics specification](https://github.com/OpenObservability/OpenMetrics/blob/main/specification/OpenMetrics.md).
+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.
