hi,all
I am using virDomainInterfaceStats to monitor the network flow of VM. But
there is some strange things.
the description of vnet in xml is:
<interface type='bridge'>
<mac address='00:16:3e:5d:aa:a8'/>
<source bridge='br0'/>
<target dev='vnet0'/>
<model type='virtio'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x03'
function='0x0'/>
</interface>
but when I call virDomainInterfaceStats to get network flow from vnet0, I
get some wrong data:
rx: 139972719907412 tx:7311107385599290735
after 2 seconds, I call it again and I get:
rx: 31 tx:7311107385599290735
another 2 seconds:
rx:155 tx:7311107385599290735
and...
rx:110 tx:7311107385599290735
(rx:receive, tx:transmit)
what do these data mean? Why there is no difference in tx at all? And
why the difference in rx is so weird?
Many thanks!
regards
zhangzhang
