If you have a large number of servers to monitor, you might want to look at
the Host sFlow agent:
http://host-sflow.sourceforge.net/
The Host sFlow agent is installed on the server and locally polls physical
server statistics and VM statistics using libvirt. The statistics are
exported using the sFlow protocol.
http://www.sflow.org/
If you want detailed network visibility then the Open vSwitch includes
sFlow monitoring of inter-VM traffic:
http://openvswitch.org/
