Ok, so I tried the new ceph dashboard by "set-prometheus-api-host"
(note "host" and not "url") and it returns the wrong data. We have 4
ceph clusters going into the same prometheus instance. How does it
know which data to pull? Do I need to pass a promql query?
The capacity widget at the top right (not using prometheus) shows 35%
of 51 TiB used (test cluster data)... This is correct. The chart shows
use capacity is 1.7 PiB, which is coming from the production cluster
(incorrect).
Ideas?

Ah yeah, probably that's why the utilization charts are empty
because it relies on
the prometheus info.
And I raised a PR to disable the new dashboard in quincy.

Hello,
We're not using prometheus within ceph (ceph dashboards show in our
grafana which is hosted elsewhere). The old dashboard showed the
metrics fine, so not sure why in a patch release we would need
to make
configuration changes to get the same metrics.... Agree it
should be
off by default.
"ceph dashboard feature disable dashboard" works to put the old
dashboard back. Thanks.
