[libvirt-users] Host and VM performance using libvirt

[Peter Phaal]

Hi Ananth,

You might want to take a look at the Host sFlow project if you have a
large KVM server pool to monitor:

The Host sFlow agent is installed on the KVM hypervisor and uses
libvirt to push the VM performance counters to a central collector,
eliminating the need to poll for metrics. In addition to VM
statistics, Host sFlow also exports the key performance metrics for
the hypervisor - CPU, memory, network and disk IO.

The open source Ganglia tool provides a scalable way to collect and
graph the metrics:
