I'm trying to diagnose who's doing what on our cluster, which suffer
from SLOW_OPS, High latency periods since Pacific.
And I can't see all pool / images in RBD stats.
I had activated RBD image stats while running Octopus, now it seems we
only need to define mgr/prometheus/rbd_

Hi,
we experienced massive node failures when a user with cephfs quota

and often over 200%. Given it's a single process, right? It makes me
think that some operations are too slow or some task is pegging the CPU
