[ceph-users] Re: Does cephfs subvolume have commands similar to `rbd perf` to query iops, bandwidth, and latency of rbd image?

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.
