Documentation Grafana documentation Linking Data links

Data links

Data links allow you to provide more granular context to your links. You can create links that include the series name or even the value under the cursor. For example, if your visualization showed four servers, you could add a data link to one or two of them.

The link itself is accessible in different ways depending on the visualization. For the Graph you need to click on a data point or line, for a panel like Stat, Gauge, or Bar Gauge you can click anywhere on the visualization to open the context menu.

You can use variables in data links to send people to a detailed dashboard with preserved data filters. For example, you could use variables to specify a time range, series, and variable selection. For more information, refer to Data link variables.

Typeahead suggestions

When creating or updating a data link, press Cmd+Space or Ctrl+Space on your keyboard to open the typeahead suggestions to more easily add variables to your URL.

Add a data link
