I'm not the expert when it comes to cephmetrics but I think (at least until very
recently) cephmetrics relies on other exporters besides the mgr module and the
node_exporter.

Hi
has anyone been able to use Mimic + cephmetric + prometheus ?
I am struggling to make it fully functional as it appears data provided
by node_exporter has a different name than the one grafana expectes
As a result of the above, only certain dashboards are being populated (
the ones ceph specific)
while others have "no data points" ( the ones server specific)
Any advice/suggestion/troubleshooting tips will be greatly appreciated
Example:
Grafana latency by server uses
node_disk_read_time_ms
but node_exporter does not provide it
curl [1]http://osd01:9100/metrics | grep node_disk_read_time
