Created attachment 995560 [details] screenshot1 Description of problem: if there is a steady data stream (e.g. 200Mbps) between 2 VMs, network indicator in VM main tab shows 0% (see screenshot) however data rate is shown correctly on Network Interfaces subtab for hosts and VMs (see screenshot) Version-Release number of selected component (if applicable): oVirt Engine Version: 3.6.0-0.0.master.20150219123521.gitafae793.el7.centos How reproducible: 100% Steps to Reproduce: 1. run data stream 200Mbps (e.g. using iperf on RHEL) between 2 VMs 2. check VM main tab Actual results: Network column on main VM tab show 0% VM network utilisation Expected results: Network utilisation shown correctly Additional info:
Likely a regression caused by me as part of the Cumulative Network Statistics feature :)
Also Network column is missing the history graph which is show for CPU and Memory
Did that exist in 3.5, or was it only added for CPU and memory to begin with?
It did not exist in 3.5, for 3.6 graphs were added for CPU and Memory, I think we should add it for network as well in order to keep the interface consistent.
this bug reproduced in 3.5 cluster too. In trying to modify vdsmfake, the networks usage percentage found as missing for VM's. engine master (3.6) running cluster compatibility 3.5.
Fix: https://gerrit.ovirt.org/#/c/43679/
This will need the vdsm patch to work: https://gerrit.ovirt.org/#/c/43679/
Tested on - 3.6.0-0.16.master.el6 with vdsm-4.17.7-1.el7ev.noarch It seems that this bug is still relevant. Sending traffic between 2 VMs and the Network column on the main VM tab still show 0% VM network utilization. Attaching screenshots

I tested this again, both on master and 3.6, and the the network utilisation shows fine in both cases. You need to wait about half a minute for monitoring and the UI to pick up the change in utilisation. Notice that you need to have vdsm patch too, so you need to update it too (must include: https://gerrit.ovirt.org/#/c/43679/ ) Maybe I could take a look at the test env to check what the problem is?
Hi Marcin Please contact me and i will show you. Network utilization is not shown under: [Virtual Machines] main tab > 'Network' utilization 0% [Hosts] main tab > 'Network' utilization 0% The only place that shows network utilization is: [Hosts] main tab > [Virtual Machines] sub tab > 'Network' Tested on - rhevm-3.6.0.2-0.1.el6.noarch and vdsm-4.17.10-5.el7ev.noarch Waited more then 15 minutes and no change, network utilization still shows 0%
Should this be ON_QA?
Burman reports that the bug is not solved. We shall continue deliberation on 3.6.1, as this should not block the release.
I checked Michaels setup and the fix is not in the code. It looks like 3.6.0 does not have it.
Indeed, I81100cc8369a is not found on the 3.6.0 branch $ git log --grep I81100cc8369abe1ff8929478e1556c4e1ab81c2a ovirt/ovirt-engine-3.6.0 |wc -l 0
Verified on - 3.6.1-0.2.el6
