In Grafana how do you get multi lines from multi-select variable and a single query

Question

I have a simple query and 2 variables, one of them is multi-select. What I'd like to do is get 1 line per multi-select.

{__name__ ="fusion:$METRIC:$POD"}

METRIC is a multi select and POD is a single select. So, I'd like to show, say, 4 metrics for the same pod.

How do I achieve this?

Answer 1

Whenever you have multi-select value in Grafana, use regex selector =~.

For PromQL queries Grafana will automatically substitute your variable with value like (val1|val2|val3).

So your query in this case would be

{__name__ =~"fusion:$METRIC:$POD"}
