For OSDs, that is correct. FYI - perf counters are also available for all Ceph daemon types (mon, mds, rgw). Dan Ryder From: 10 minus [mailto:t10tennn@xxxxxxxxx]
Thanks Dan, If I understand correctly , perf_counters have to run against OSDs ( I mean for every OSD I have to run a check). On Fri, Nov 14, 2014 at 8:44 PM, Dan Ryder (daryder) <daryder@xxxxxxxxx> wrote: 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. Dan Ryder From: ceph-users [mailto:ceph-users-bounces@xxxxxxxxxxxxxx]
On Behalf Of 10 minus 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 .
