Is it possible to have one side of a query limit the results of another
part of the same query?
For example; I want an alert query for when the count of all instances in a
clustered service are not equal to what the instance is reporting based on
a label's value being equal in both sides of the query (in this case; there
are many nodes that run the same service but are part of different
clusters:)
*redis_cluster_known_nodes != scalar(count(up{service=~"redis-exporter"}))*
The shared label value would be something like, *group="cluster-a" *and
should not evaluate metrics where *group="cluster-b"*
Thanks in advance!
