Rate your experience required. Comments required. Instead of hard-coding details such as server, application, and sensor names in metric queries, you can use variables. Grafana lists these variables in dropdown select boxes at the top of the dashboard to help you change the data displayed in your dashboard. Grafana refers to such variables as template variables. For an introduction to templating and template variables, refer to the Templating and Add and manage variables documentation. For details, refer to the Graphite docs on the autocomplete API for tags. Multi-value variables in tag queries use the advanced formatting syntax for variables introduced in Grafana v5. Non-tag queries use the default glob formatting for multi-value variables. For more information, refer to Advanced variable format options. For example, a query like prod. The results contain all possible values occurring only at the last level of the query.

Rate your experience required. Comments required. Navigate to the dashboard you want to make a variable for and click the Dashboard settings gear icon at the top of the page. Query variables enable you to write a data source query that can return a list of metric names, tag values, or keys. For example, a query variable might return a list of server names, sensor IDs, or data centers. The variable values change as they dynamically fetch options with a data source query. Query variables are generally only supported for strings.

Hello there, I have the same problem as yours. However, I read the official documentation of value mapping and it says that value mapping accepts variables, which is pretty confusing. Have you figured out this problem? Is it us that use variables incorrectly or it is actually a function that had not yet been added to Grafana? We also have the same issue where we wish to convert a query values to a more friendly display names base on a variable or a dynamic value mapping based on a query. Im facing the same problem. I want to display the query values to show in a more friendly display too, did u fixed this? Hi horselessname , natasha1 and other users. I know that the original post is almost 2 years old and not sure if all of the users are still active or have found a possible solution or workaround.

In principle by using the API to update a dashboard JSON definition, you should also be able to set different default values - which are part of the definition - as well as make other modification. I have a dashboard with the variable defined in it and now I want to update the values of the variable using APIs. Got it. Can you share the full error message, including status code? Also a skeleton of your request, if possible you can leave out the dashboard definition. It sounds like an issue with the API usage. Are you definitely following the JSON schema described here? Your JSON payload needs to contain a dashboard object with the new dashboard definition, but same dashboard id as the existing dashboard. I think you might also have to set overwrite: true at the top level outside the dashboard payload. But in your request it looks like you do.
