Configure data links

This documentation topic is designed for Grafana workspaces that support Grafana version 9.x.

For Grafana workspaces that support Grafana version 10.x, see Working in Grafana version 10.

For Grafana workspaces that support Grafana version 8.x, see Working in Grafana version 8.

You can use data link variables or data links to create links between panels.

You can use variables in data links to refer to series fields, labels, and values. For more information about data links, see Data links.

To see a list of available variables, type $ in the data link URL field to see a list of variables that you can use.

Note

These variables changed in 6.4, so if you have an older version of Grafana, then use the version picker to select docs for an older version of Grafana.

You can also use template variables in your data links URLs, see Adding and managing dashboard variables.

Time range panel variables

These variables allow you to include the current time range in the data link URL.

  • __url_time_range - current dashboard’s time range (i.e. ?from=now-6h&to=now)

  • $__from and $__to - For more information, see Global variables.

Series variables

Series specific variables are available under __series namespace:

  • __series.name - series name to the URL

Field variables

Field-specific variables are available under __field namespace:

  • __field.name - the name of the field

  • __field.labels.<LABEL> - label’s value to the URL. If your label contains dots, then use __field.labels["<LABEL>"] syntax.

Value variables

Value-specific variables are available under __value namespace:

  • __value.time - value’s timestamp (Unix ms epoch) to the URL (i.e. ?time=1560268814105)

  • __value.raw - raw value

  • __value.numeric - numeric representation of a value

  • __value.text - text representation of a value

  • __value.calc - calculation name if the value is result of calculation

Template variables

When linking to another dashboard that uses template variables, select variable values for whoever clicks the link.

${var-myvar:queryparam} - where var-myvar is the name of the template variable that matches one in the current dashboard that you want to use.

Variable state Result in the created URL
selected one value var-myvar=value1
selected multiple values var-myvar=value1&var-myvar=value2
selected All var-myvar=All

If you want to add all of the current dashboard’s variables to the URL, then use ${__all_variables}.

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, see 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.

  1. Hover your cursor over the panel that you want to add a link to and then press e. Or click the dropdown arrow next to the panel title and then click Edit.

  2. On the Field tab, scroll down to the Data links section.

  3. Expand Data links and then click Add link.

  4. Enter a Title. Title is a human-readable label for the link that will be displayed in the UI.

  5. Enter the URL you want to link to.

    You can even add one of the template variables defined in the dashboard. Click in the URL field and then type $ or press Ctrl+Space or Cmd+Space to see a list of available variables. By adding template variables to your panel link, the link sends the user to the right context, with the relevant variables already set. For more information, see Data link variables.

  6. If you want the link to open in a new tab, then select Open in a new tab.

  7. Click Save to save changes and close the window.

  8. Click Save in the upper right to save your changes to the dashboard.

  1. On the Field tab, find the link that you want to make changes to.

  2. Click the Edit (pencil) icon to open the Edit link window.

  3. Make any necessary changes.

  4. Click Save to save changes and close the window.

  5. Click Save in the upper right to save your changes to the dashboard.
