Hi Ananth, You might want to take a look at the Host sFlow project if you have a large KVM server pool to monitor: http://blog.sflow.com/2010/10/kvm.html 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: http://blog.sflow.com/2012/01/using-ganglia-to-monitor-virtual.html Peter On Sun, Jan 8, 2012 at 11:11 PM, Ananth <cbananth@gmail.com> wrote:

Hi,

Is there any libvirt API for measuring the Host and VM performance parameters. Or is there any virsh command implementing the same for KVM? eg: CPU utilization, memory utilization, load percentage, CPU Mhz etc.,
