Hi In general you can take and tune the probes at var/remotes/im/kvm.d:
1.- CPU is gathered by kvm.rb using top. (free_cpu is associated to the idle parameter while used is total - free) 2.- In the same way, memory is obtained from virsh nodeinfo. If you plan to use ballooning, you need to adapt the probe. Currently it is getting the "Memory size" information Cheers Ruben On Thu, May 10, 2012 at 5:05 PM, Antonio Carlos Salzvedel Furtado Junior <acsf...@inf.ufpr.br> wrote: > I noticed it too when using KVM.
