I create a dashboard variable with type “Data source” and make sure in has “All” option:
The preview of values returns “All” among a bunch of individual datasources (they are all Elasticsearch type).
Then i create another dashboard variable $Deployment with type “Query” and make sure it references to the datasource variable that i created earlier:
Now, back in the dashboard when i set the $region variable value to “All”, i expect the $Deployment variable to contain all the the values from all the regions. But it doesnt happen - it displays only the values from the alphabetically first individual datasource.
Why is that? Is there any workaround?
