Documentation Grafana Cloud Knowledge graph Advanced configuration Map metrics Amends

Amends

The knowledge graph records amends such as new versions, configuration updates, and scale up and scale down events by observing changes in metric label values and metric values. Amends are annotated as blue bars on RCA workbench.

For example, the metric redis_instance_info has a label redis_version, and the label value is tracked by the knowledge graph as a new normalized label version to record new versions.
