This really isn't feasible right now as a starter project: doing it "for real" requires all OSDs track all clients and IOs and then a central location to receive that data and correlate it. We discussed a sampling implementation for ceph-mgr recently in the Ceph Dev Monthly and I think work is upcoming to enable it, but I'm not sure what kind of timeline it's on. -Greg _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
