Add a custom variable
Use a custom variable for a value that does not change, such as a number or a string.
For example, if you have server names or region names that never change, then you might want to create them as custom variables rather than query variables. Because they do not change, you might use them in chained variables rather than other query variables. That would reduce the number of queries Grafana must send when chained variables are updated.
Enter General options
- Navigate to the dashboard you want to make a variable for and then click the Dashboard settings (gear) icon at the top of the page.
- On the Variables tab, click New.
- Enter a Name for your variable.

Enter Custom Options
- In the Values separated by comma list, enter the values for this variable in a comma-separated list. You can include numbers, strings, or key/value pairs separated by a space and a colon. For example,
key1 : value1,key2 : value2.
- (optional) Enter Selection Options.
- In Preview of values, Grafana displays a list of the current variable values. Review them to ensure they match what you expect.
