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]({{< relref "/docs/grafana/latest/datasources/" >}}) 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]({{< relref "/docs/grafana/latest/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]({{< relref "/docs/grafana/latest/explore/#split-and-compare" >}}).
Explore visualizations that currently support showing links based on correlations:
- [Logs Panel]({{< relref "./use-correlations-in-visualizations#correlations-in-logs-panel">}})
- [Table]({{< relref "./use-correlations-in-visualizations#correlations-in-table">}})
You can configure correlations using [Administration > Correlation page]({{< relref "/docs/grafana/latest/administration/" >}}) or with [provisioning]({{< relref "/docs/grafana/latest/administration/provisioning" >}}).
Note: Correlations are available in Grafana 10.0+ as an opt-in beta feature. Modify Grafana [configuration file]({{< relref "/docs/grafana/latest/setup-grafana/configure-grafana/#configuration-file-location" >}}) to enable the
correlations[feature toggle]({{< relref "/docs/grafana/latest/setup-grafana/configure-grafana/#feature_toggles" >}}) to use it.
Example of how links work in Explore once set up
