One way to apply the same query to various values in Grafana is by using template variables.

1. Create a variable by clicking on the "Variables" icon in the left-hand side menu.
2. Define the type of variable (e.g. Query, Custom, etc.) and the query to fetch the list of values.
3. Add the variable to the queries (for example, use $variable_name instead of a hardcoded value).
4. In the dashboard settings, set the values for the variable (e.g. a list of servers, regions, etc.).
5. Save and the queries will update to show the data for the selected values.

This allows for easy filtering and comparison of data across multiple values, without having to manually edit the query each time.
