We scrape all mgr endpoints since we use external Prometheus clusters,
as well. The query results will have {instance=activemgrhost}. The
dashboards in upstream don't have multiple cluster support, so we have
to modify them to work with our deployments since we have multiple
ceph clusters being polled by Prometheus clusters. We effectively add
instance regular expressions to all the queries on the dashboards, and
a variable for the dashboard itself, to support getting the list of
clusters via a label_values call on one of the ceph_exporter metrics +
regular expression to parse out the part after the hostname portion of
the fqdn.I don't think the current dashboards are intended for use outside the internal Prometheus deployments, but we definitely intended (at some point when time permitted) to try and submit patches that would work for both use-cases, since it's painful to continually update the dashboards on every release.
