That makes sense. The ipv6 BUG can lead to the issue you described. In the current implementation whenever a mgr failover takes place, prometheus configuration (when using the monitoring stack deployed by Ceph) is updated automatically to point to the new active mgr. Unfortunately it's not easy to have active services running in the standby mgr. At most, we can do some redirection as we do in the dashboard.
I've had a little look at the standby mode in the prometheus module; it can already figure out the active metrics URL via module.get_active_uri(), so it looks like adding an additional "redirect" standby_behaviour that emits an HTTPRedirect to the active URI wouldn't be too hard. Is that a change you'd be in principle willing to accept?
So far we haven't had the need to do that. Next releases will come with the new mgmt-gateway service introduced in [1] and [2] which will make it easy to have a single entry point to the cluster handling HA transparently in the backend.
Interesting, thanks. This would then be configured as a single endpoint (which one could presumably redeploy from time to time) that external monitoring could be pointed at?
