Thanks Dan, If I understand correctly , perf_counters have to run against OSDs ( I mean for every OSD I have to run a check).

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 .
