Correlations
You can create interactive links for Explore visualizations to run queries related to presented data by setting up Correlations.
A correlation defines how data in one data source is used to query data in another data source. Some examples:
- an application name returned in a logs data source can be used to query metrics related to that application in a metrics data source, or
- a user name returned by an SQL data source can be used to query logs related to that particular user in a logs data source
Explore takes user-defined correlations to display links inside the visualizations. You can click on a link to run the related query and see results in Explore Split View.
Explore visualizations that currently support showing links based on correlations:
You can configure correlations using provisioning, the Administration > Plugins and data > Correlations page in Grafana or directly in Explore.
