Orphaned worker Clusters::Applications::CheckPrometheusHealthWorker
The Clusters::Applications::CheckPrometheusHealthWorker
is defined in our codebase. But as far as I can tell, it doesn't have a way to get executed.
We looked into Cron workers without a schedule in #321780 (comment 515147147). It seems like this Cron worker was added in !27360 (merged), but it does not have a schedule, nor does it get scheduled from the codebase.
Can this worker be removed? That would be one extra queue to watch, as we've seen in gitlab-com/gl-infra&194 (closed), having Sidekiq watch queues that don't ever need anything is a bit wasteful.
