I am trying to create a Node Graph from data that is collected by Loki and Prometheus. I have the queries that return the data that I want, and they are in the correct table format after applying some transformation. I end up with two separate series or frames (newbie here) that are named by the comma separate list of their fields - for example “id, source, target, mainstat, color”.
Node Graph does generate a nice graphic (thank you) but it doesn’t seem to recognize many of the fields, such as “mainstat”. It does recognize “color”. Now I have figured out that I need to name the data series (or frames) exactly as “edges” and “nodes”. But after some days of struggle I have not been able to figure out how to do that.
How can I set the name of a series that is the output of a transformation in a dashboard so that Node Graph will understand what it is?
Grafana 12.02 CE docker container on Ubuntu 24.04LTS
Much information points me to a transformation “Rename by Regex”, which doesn’t exist on my instance. Only “Rename fields by Regex”.
