sosreport please

> sosreport please

I already gave access to the test setup for further debugging. Hope you gathered all the required details during that time?

Comment 5 Bala.FA 2014-06-27 22:26:17 EDT

We found the issue with sysstat and it corrected itself next day ie ovirtmgmt bridge is found in sadf output.

Not sure why it happened.  Will be investigated and fixed accordingly

Comment 6 Shubhendu Tripathi 2014-07-01 02:55:24 EDT

Similar issues with sadf output is seen for other physical services like Memory, Swap and CPU Utilization as well. The output is corrupted on first day but automatically gets corrected for the next day after midnight and services start working properly and graphs are displayed correctly.

Comment 7 Dusmant 2014-07-03 01:29:08 EDT

We should document it, so that, end-user does not get confused or feels "what's wrong with this?"

Comment 9 Shubhendu Tripathi 2014-07-10 04:22:57 EDT

As Bala confirmed there is an issue with sadf and at the time of day change (midnight) the sadf does not return any value.

Bala, please confirm the same.

Comment 10 Bala.FA 2014-07-10 05:25:02 EDT

Yes.  It worked that way.  We are looking into sysstat code how to fix this issue.

Comment 12 Dusmant 2014-09-25 03:15:44 EDT

Moving it to 3.0.3
