Re: [libvirt-users] How to collect the VM bandwidth usage utilization

If you are trying to monitor KVM, XenServer or Xen then you might want to take a look at the Host sFlow project: http://host-sflow.sourceforge.net/ The Host sFlow agent is installed on the hypervisor and exports libvirt metrics for the VMs. sFlow uses a push model, continually streaming the metrics as UDP datagrams to a central collector. Pushing the statistics scales much better than polling and automatically adapts as VMs are added, moved and removed. Take a look at Ganglia for collecting and displaying the metrics: http://ganglia.sourceforge.net/ If you are using the latest versions of XCP or XenServer, then you can use sFlow monitoring in the Open vSwitch to get detailed visibility into traffic flows: http://openvswitch.org/ Open vSwitch supports both sFlow and NetFlow for traffic monitoring, the following article provides a comparison: http://blog.sflow.com/2011/10/comparing-sflow-and-netflow-in-vswitch.html Peter On Sun, Oct 23, 2011 at 11:12 PM, vmnode guy <vmnodeguy(a)gmail.com&gt; wrote:
