RedisTooManyMasters with multiple Redis clusters
exolab opened this issue · comments
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?
Interesting. Where/how was the alert created? Is it part the provided grafana dashboard?
From your description it sounds likely that the query is wrong.
Thank you for your answer.
We are seeing it in Alertmanager. I have now created an issue where the rule is actually defined. ;)
