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/ For more information, see: http://blog.sflow.com/2010/10/kvm.html http://blog.sflow.com/2010/10/sflowtrend-adds-server-performance.html Peter
