AFAIK this was solved by OpenStack folks following what Vladimir suggested:
keepalived + haproxy for grafana and prometheus (alertmanager has it's own
gossip-based HA).
Please find attached (if the mailing list permits) a document where we
discussed different approaches to provide HA to the Ceph monitoring stack.
And there's also an open tracker issue for this activity:
