[ceph-users] Fw:Re: "ceph daemon osd.x ops" shows different number from "ceph osd status <bucket>"

21 Jul 2020

      aha, thanks very much for pointing out, Anthony!

Just a summary for the screenshot pasted in my previous email. Based on my understanding, "ceph daemon osd.x ops" or "ceph daemon osd.x dump_ops_in_flight" shows the ops currently being processed in the osd.x. I also noticed that there is another ceph cli that shows the number of ops with particular osds, i.e. "ceph osd status {<bucket>}", and the number doesn't match with the daemon one, nor "ceph daemon osd.x dump_historic_ops". I haven't looked into the code yet, and just try to get a quick help from the community about how the ops number from "ceph osd status {<bucket>}" is calculated? Is it a statistical value?

Thanks!

Your messages are very hard to read.

"ceph daemon osd.x ops" shows ops currently in flight, the number is different from "ceph osd status <bucket&gt;". Is the number of ops in "ceph osd status <bucket&gt;" also the ops currently in flight?
