Hi,
Take a look at the built in perf counters - http://ceph.com/docs/master/dev/perf_counters/. Through this you can get individual daemon performance as well as some cluster level statistics.
Other (cluster-level) disk space utilization and pool utilization/performance is available through “ceph df detail”. Hope this helps.

Subject: Performance data collection for Ceph
Hi,
I 'm trying to collect performance data for Ceph
I 'm looking to run some commands .. on regular intervals. to collect data.
Apart from "ceph osd perf" . Are there other commands one can use.
Can I also track how much data is being replicated ?
Does Ceph maintain performance counters for individual OSDs ?
Something on the lines of zpool iostat .
