Thanks I’ll have a look into that. Are you able to advise on substituting my query into the format ‘foo or on (x,y,z) bar * 0’ like you suggested.
I tried one but got unexpected expression so I’m obviously getting the syntax wrong….! I suppose that if there are for example no nodes that are enabled but not available, would Prometheus actually know the pools that don’t match this because they theory they would not be returned at all in the query, nevermind the count by.
