Grafana has a query editor that exposes the capabilities of your data source and allows you to query the metrics that it contains. Grafana provides a custom query editor for each data source, including the data source used to integrate Grafana with Prometheus. You can use the query editor to structure queries that allow you to visualize the metrics that are stored in the Prometheus database.
