Sorry for the late reply. We actually discussed this aspect during one
of the calls we had when discussing the Grafana dashboard integration
into the Ceph Manager Dashboard. Such kind of state information is
somewhat difficult to track and visualize using Prometheus/Grafana (or
any other TSDB, FWIW), as you can't store the actual reasons for why the
cluster is in HEALTH_WARN or HEALTH_ERR, for example.

We are therefore considering displaying this information in the form of
"native" widgets on the Manager Dashboard, and using the Grafana
dashboards for visualizing the other more suitable performance metrics.
