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.
You don't mention if it is a paravirt or HVM guest. If it is a HVM guest, then you don't get any statistics, unless the paravirt drivers are installed.
