Hello,

I am wondering if there is any detailed documentation for obtaining I/O 
statistics for a Ceph cluster.
The important metrics I'm looking for are: the number of operations, size of 
operations, and latency of operations - by operations I'm referring to 
read/write.

I've seen what look like the right statistics after running a "ceph 
--admin-daemon /var/run/ceph/ceph-osd.0.asok perf dump", and looking under the 
"osd" section, but I would like to confirm what exactly these stats represent.

If there is any documentation you could point me to, or any other pertinent 
information to offer it would be very helpful.

Thanks,
Dan Ryder
