I think you are looking for inotify/fanotify events for Ceph. Usually these are implemented for local file system. Ceph being a networked file system, it will not be easy to implement and will involve network traffic to generate events.
Not sure it is in the plan though.

This isn't a feature that CephFS has right now. Still, I would be
interested to know what protocol/format your server would consume
these kinds of notifications in?
