Ceph file change monitor

[siva kumar <85siva@xxxxxxxxx>]

Dear Team,

We are using ceph storage & cephFS for mounting .

Our configuration :

3 osd

3 monitor

4 clients .

ceph version 0.94.5 (9764da52395923e0b32908d83a9f7304401fee43)

We would like to get file change notifications like what is the event (ADDED, MODIFIED,DELETED) and for which file the event has occurred. These notifications should be sent to our server.

How to get these notifications?

Ultimately we would like to add our custom file watch notification hooks to ceph so that we can handle this notifications by our self .

Additional Info :

[test@ceph-zclient1 ~]$ ceph -s
