Hi Fyodor, Ceph Grafana Dashboards come from 2 different sources: Node Exporter metrics and the Ceph Exporter ones (a Python module running inside ceph-mgr). I'd check the following steps: 1. Ceph services are running (OSD, MDS, RGW, ...), otherwise there might be no data to feed the Ceph-specific charts. 2. The Ceph exporter is running ("ceph mgr services") and it's URL is reachable from the Prometheus server. 3. The Prometheus server contains "ceph_.*" metrics (you may simply visit the Prometheus Web UI and start typing "ceph": if nothing shows up it means that there are no Ceph metrics stored). 4. In the Prometheus Web UI you may check the target section: the Ceph target should be green. Hope this helps you find out the issue.

Hi!
I installed fresh cluster 16.2.4 as described in https://docs.ceph.com/en/latest/cephadm/#cephadm
Everything works except for one thing: there are only graphics in the hosts / overall performance, (only the CPU and the network). In all other places the inscription "no data".
What could I have done wrong?
