"RBD Overview" and "RBD details" dashboards are all empty

[Yoshi Kadokawa]

"RBD Overview" and "RBD details" dashboards in Grafana are all empty as you can see in the attached screenshot.
Because of this "Overall performance" in Ceph Dashboard => Block => Images
is also empty.

The environment is OpenStack Yoga + Ceph Quincy on Ubuntu Focal.
I have confirmed that there are several pools been created but no rbd_stats_pools[0] is configured.

$ sudo ceph osd pool ls
.mgr
default.rgw.buckets.data
default.rgw.control
default.rgw.data.root
default.rgw.gc
default.rgw.log
default.rgw.intent-log
default.rgw.meta
default.rgw.otp
default.rgw.usage
default.rgw.users.keys
default.rgw.users.email
default.rgw.users.swift
default.rgw.users.uid
default.rgw.buckets.extra
default.rgw.buckets.index
.rgw.root
glance
cinder-ceph

$ sudo ceph config get mgr mgr/prometheus/rbd_stats_pools
<empty>

This can be workarounded by conifugring the following. (Adding cinder-ceph and glance for example)

$ sudo ceph config set mgr mgr/prometheus/rbd_stats_pools "cinder-ceph,glance"

Then the dashboards in Grafana will show with data.
However, for the dashboards in the Ceph Dashboard, you will need to workaround because of the other bug[1].

Steps to reproduce:
juju deploy openstack-base
juju deploy ceph-dashboard --channel quincy/stable
juju deploy telegraf
juju deploy grafana
juju deploy prometheus2 prometheus

juju config telegraf hostname="{host}"
juju config grafana anonymous=True
juju config grafana allow_embedding=True
juju config grafana install_plugins="https://storage.googleapis.com/plugins-community/vonage-status-panel/release/1.0.11/vonage-status-panel-1.0.11.zip,https://storage.googleapis.com/plugins-community/grafana-piechart-panel/release/1.6.2/grafana-piechart-panel-1.6.2.zip"

GRAFANA_IP=$(juju run --unit grafana/leader \
  "network-get --bind-address website")
juju config ceph-dashboard grafana-api-url=https://${GRAFANA_IP}:3000
