<ul><li><strong>Assignee</strong> deleted (<del><i>John Spray</i></del>)</li></ul><p>The get_pool_list_with_stats implementation looks strange to me.</p>
<p>It seems to be trying to construct some deque time series in pool_stats, but pool_stats is a local that's construct each time the function is called. The later call to get_rate is probably always returning 0 because the length of the series is only ever 1.</p>
<p>Look at how update_pool_stats is used in the luminous dashboard -- it's called each time we get a pg_summary notification, and maintains the time series as an attribute of the MgrModule instance, so that it's always there when something else wants to read it.</p> Dashboard - Bug #34320: mgr/dashboard: Read/Write OPS in pool stats always show 0https://tracker.ceph.com/issues/34320?journal_id=1196482018-08-30T13:49:52ZVolker Theile

<ul></ul><p>Just to elaborate on this a bit (thank you John for the clarification on IRC): this needs to be fixed in the Ceph Manager dashboard module backend:</p>
<p><em>The underlying ceph-mgr bits just give the current statistics (via the pgmap summary) -- the calculation of the rate would happen in the dashboard</em></p> Dashboard - Bug #34320: mgr/dashboard: Read/Write OPS in pool stats always show 0https://tracker.ceph.com/issues/34320?journal_id=1201832018-09-07T13:56:52ZLenz Grimmer
