Prometheus data source

Prometheus is an open source monitoring system and time series database that scrapes and stores metrics used for monitoring and alerting.

Grafana includes built-in support for Prometheus, so you don’t need to install a plugin. Write queries using PromQL in the query editor, or use Metrics Drilldown to explore metrics without writing queries. The Prometheus data source also works with other projects that implement the Prometheus querying API, including Grafana Mimir and Thanos.
