Ugh. Ok, then it looks like the key info here is to get the data from the osd/mon sockets. Forgive me for not digging too deep yet, but it looks like I would do something like: ceph --admin-daemon /var/run/ceph/ceph-osd.4.asok perf dump * which of that data is read/write bytes? * Is that data for the entire cluster, or just that osd? (would I need to read data from each individual osd sock in the cluster?) Thanks, Blade.
