Description

The ceph cluster deploys ceph and non-ceph daemons.

When a ceph daemon fails, ceph itself raises a healthcheck which is propagated through the prometheus alert rules to alert manager to the 'outside world'. However, when a non-ceph daemon fails (haproxy, keepalived, ganesha etc) it can go unnoticed at both the ceph CLI and prometheus/alertmanager.

Ideally the failure of any daemon controlled by cephadm should be flagged to the CLI as a healthcheck and therefore Prometheus/AlertManager
