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.

Cloud-managed Prometheus services

{{< admonition type="note" >}} In Grafana 13, the core Prometheus data source no longer supports SigV4 (AWS) or Azure AD authentication. These authentication methods have been migrated to dedicated plugins:

• Amazon Managed Service for Prometheus — Use the Amazon Managed Service for Prometheus data source. For migration details, refer to AWS authentication (deprecated).
• Azure Monitor Managed Service for Prometheus — Use the Azure Monitor Managed Service for Prometheus data source. For migration details, refer to Azure authentication (deprecated).

Existing data sources using these methods are automatically migrated on startup. {{< /admonition >}}
