I have a metric with label , say subject, having different values. I need to get list of instances subject !~“some subject”
if i run
metric{subject!~“.some subject.”)
i get result with all other subjects and all instances.
If i run
count by(instance) (metric{subject!~“.some subject.”) )
i get all instances
i can run
metric{subject~=".some subject.) then i get only instances where that subject is present but then how can i subtract this list from all instance list?
something like
count by (instance) (metric) - (count by (instance) (metric{subject~=“.some subject.”) )
how to do that?
Thanks
