Grafana is an open-source visualisation tool. It does not store data, but consumes data sources to create real-time graphs displayed on custom dashboards. Data sources include Prometheus, Graphite, Logit and CloudWatch. The query language of the data store, such as PromQL for Prometheus, is used to construct the graphs.

You can click on a metric in a graph to show only that metric, or you

Annotations on charts show events such as deploys:
