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?

Dan.

Here is the output of vdsClient

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

Here is the output of vdsClient
http://ur1.ca/nporl
'bond0': {'name': 'bond0',
'rxDropped': '0',
'rxErrors': '0',
'rxRate': '7.1',
'speed': '20000',

'txDropped': '0',

'txRate': '0.3'},
'ovirtmgmt': {'name': 'ovirtmgmt',

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.

Maybe related to https://bugzilla.redhat.com/show_bug.cgi?id=1108144
Could you show the result of the following command, executed on the host
while the network test is happening?
# vdsClient -s 0 getVdsStats
VDSM Version: vdsm-4.16.20-1.3.el6rhs.x86_64
Ovirt release : both 3.5 and 3.6
