Hello - I am using Grafana 8.3.4 with a Graphite data source. Both Grafana and Graphite reside on CentoOS 8. I have the following panel:
I am trying to change the display name to use just the text that follows the period. In the first series I want to display only VRF_Training and the second series should be Home, etc. I believe the proper way to do this is to create a dashboard variable that extracts the field of interest and then update the panel Standard options called Display name.
When I change the Display name to $pages my thinking is that I should see the the last part of the query results. However, instead what i am seeing is
Can someone tell me what I am going wrong and how to accomplish my goal?
