A regex expression “{.*” that I was using previously worked flawlessly. I do not remember what the version of the Grafana was when the “Rename by regex” worked but since June 2022 it has been broken.
The names come like this:
guilds{instance="localhost:9284", job="thothbot"}
old_stats{instance="localhost:9284", job="thothbot"}
slash_stats{instance="localhost:9284", job="thothbot"}
