Ceph » mgr » Dashboard

Hi A. Saber Shenouda,

Can you provide mgr logs, actions/steps performed for read/write activity in the pool?

The aim is to be able to reproduce the bug (currently not reproducible in my local environment).

Thanks in advance.

I observe similar behavior on ceph 17.2.5 - it looks like ALL values for "read ops" and "write ops" greater than 999/s are presented as "NaN Undefined/s" (I have never seen value for ops/s >= 1000 there, but smaller values are presented correctly). Problem is 100% reproducible both in firefox and chrome/chromium browsers. (I don't know if it's important - I use non-english (Polish) browsers localization).
When I clicked-down data returned by "/pool?stats=true" request mentioned above I see "good looking" values in json data for pool's "rd" or "wr" stats elements (shown as "NaN" in html output page), example below (and rate value is >=1000 in these cases):

    "rd": {
        "latest": 1975201324,
        "rate": 7712.354756671364,
        "rates": [

            ]
        ]
    }

For me it looks like problem in javascript generating html output from json data..
