With the 5.0 release of our Grafana plugin, you can now scope Grafana template variables to a particular UQL filter expression. In that filter expression, you can also reference existing defined template variables.
For example, you want to create a dashboard with two template variables for service and operation. And selecting a service should scope operation values to that service. This is now possible with a UQL filter expression like service == $service.
You can use any filter expression to limit the values returned. We can limit operation to a particular service and filter to server entrypoints with:
service == $service && span.kind == server
Also, with this release the minimum Grafana version supported is 9.5.0.
