hi all
I'm using Xen on CentOS.I wanna monitor the network activity of a domain. When I use Domain.InterfaceStats( ... ), which is the C# binding of virDomainInterfaceStats, it returns -1.
I wonder if the function is not supported by Xen. So I using "domifstat", and I get
vif1.0 rx_bytes 0
vif1.0 rx_packets 0
vif1.0 rx_errs 0
vif1.0 rx_drop 0
vif1.0 tx_bytes 0
vif1.0 tx_packets 0
vif1.0 tx_errs 0
vif1.0 tx_drop 0
but it never change even when I use that domain to ping another.
virsh version:
Compiled against library: libvir 0.8.4
Using library: libvir 0.8.4
Using API: Xen 3.0.1
Running hypervisor: Xen 3.3.0
My question is, is Xen not support virDomainInterfaceStats or is somewhere I've gone wrong, that I can't get the network i/o statistics?
Thank you !
