Hi all,

Does cephfs subvolume have commands similar to rbd perf to query iops,
bandwidth, and latency of rbd image?  `ceph fs perf stats` shows metrics of
the client side, not the metrics of the cephfs subvolume. What I want to
get is the metrics at the subvolume level like below.

rbd: waiting for initial image stats
