Text box variables display a free text input field with an optional default value. For example, key1 : value1,key2 : value2. You can include numbers, strings, or key/value pairs separated by a space and a colon.
In the Values separated by comma list, enter the values for this variable in a comma-separated list. That would reduce the number of queries Grafana must send when chained variables are updated. Because they do not change, you might use them in chained variables rather than other query variables. Use a custom variable for a value that does not change, such as a number or a string.įor 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. Click Add to add the variable to the dashboard. Review them to ensure they match what you expect. In Preview of values, Grafana displays a list of the current variable values. The default option, Disabled, means that the order of options returned by your data source query will be used. In the Sort list, select the sort order for values to be displayed in the dropdown list. To see examples, refer to Filter variables with regex. (Optional) In the Regex field, type a regex expression to filter or capture specific parts of the names returned by your data source query. If you need more room in a single input field query editor, then hover your cursor over the lines in the lower right corner of the field and drag downward to expand. Some data sources have custom query editors. The query field varies according to your data source. Only use this option if your variable options query contains a time range filter or is dependent on the dashboard time range. On Time Range Change: Queries the data source when the dashboard time range changes. 
This slows down dashboard loading, because the variable query needs to be completed before dashboard can be initialized.
On Dashboard Load: Queries the data source every time the dashboard loads.

In the Refresh list, select when the variable should update options.For more information about data sources, refer to Add a data source. In the Data source list, select the target data source for the query.For more information, refer to the documentation for your data source. Note: Query expressions are different for each data source. Grafana detects this and automatically refreshes a variable when one of its linked variables change. Query expressions can contain references to other variables and in effect create linked variables. For the Azure data source, for example, you can use the tostring function for this purpose. If your query returns numbers or any other data type, you might need to convert them to strings in order to use them as variables. Query variables are generally only supported for strings. The variable values change as they dynamically fetch options with a data source query. For example, a query variable might return a list of server names, sensor IDs, or data centers. Query variables enable you to write a data source query that can return a list of metric names, tag values, or keys. Variable: No variable dropdown is displayed on the dashboard.Label: The variable dropdown only displays the selected variable value and a down arrow.
No selection (blank): The variable dropdown displays the variable Name or Label value. If you don’t enter a display name, then the dropdown label is the variable name. (Optional) In Label, enter the display name of the variable dropdown. Navigate to the dashboard you want to make a variable for and click the Dashboard settings (gear) icon at the top of the page. You must enter general options for any type of variable that you create. Variable queries can contain other variables.
