This PR (https://github.com/ceph/ceph/pull/25114) added rbd client side perf counters and this PR (https://github.com/ceph/ceph/pull/25358) will add those counters as prometheus metrics. There is also room for an "rbd top" tool, though I haven't seen any code for this. > I'm sure Mykola (the author of both PRs) could go into more detail if needed.
