A much richer and more precise source of information would be the various
performance counters and using collectd to feed them into graphite and

I'm using the DWM one, YMMV.
Thanks much for your reply, Christian.
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.
