Network statistics shown in ovirt doesn't look correct.
Hi, I have a strange issue with the network traffic shown in oVirt webadmin portal. I have 2 10 Gb network card and I have created bond out of them. I have used *'iperf*' command to generate10 Gbps traffic and I can see that getting reflected in my nagios monitoring. Also iperf command confirms that it transferred the data at the rate of 9.38 Gbits/sec. But oVirt Ui shows only 1500 Mbps. I am not sure how oVirt shows very low traffic. Anyone experiencing the similar problem? VDSM Version: vdsm-4.16.20-1.3.el6rhs.x86_64 Ovirt release : both 3.5 and 3.6 I have attached the relevant screen shots here. Regards, Ramesh

Can you provide the output of vdsClient -s 0 getVdsStats when iperf is running? Could you see if a similar issue happens with a new 3.6 vdsm? Regards, Dan.

Here is the output of vdsClient http://ur1.ca/nporl

I have to re-install the machine with 3.6. I will update u after doing the same. Regards, Ramesh

Here is the output of vdsClient http://ur1.ca/nporl
'bond0': {'name': 'bond0', 'rxDropped': '0', 'rxErrors': '0', 'rxRate': '7.1', 'speed': '20000', 'state': 'up', 'txDropped': '0', 'txErrors': '0', 'txRate': '0.3'}, 'ovirtmgmt': {'name': 'ovirtmgmt', 'rxDropped': '0', 'rxErrors': '0', 'rxRate': '100.0', 'speed': '1000', 'state': 'up', 'txDropped': '0', 'txErrors': '0', 'txRate': '5.5'}} This may very well be a case of Bug 1120778 - align reported speeds for physical bond and bridge but I'm not sure when we are going to fix it, since 3.6 vdsm reports absolute rx/tx values, which lets Engine provide more sensible data to the user.
