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.
Can you provide the output of
vdsClient -s 0 getVdsStats
when iperf is running?
Here is the output of vdsClient

'bond0': {'name': 'bond0',
                             'rxDropped': '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.

Could you see if a similar issue happens with a new 3.6 vdsm?
I have to re-install the machine with 3.6. I will update u after doing the
same.
