RedisTooManyMasters in a multi-cluster setup

Open exolab opened this issue 9 months ago • 3 comments

Hi,

We are seeing this alert after deploying multiple Redis clusters in different namespaces. AFAICT Redis itself does not consider this setup a problem.

Does the alert not take this scenario into account, or are we mistaken in thinking we do not have a real problem?

Shouldn't the query be

count(redis_instance_info{role="master"}) by (namespace) > 1 or something similar that takes this scenario into account?
