Hello,

I was wondering about sar under xen: is it more logical to install it on dom0 or in each domU?
about disk i/o it should be able to give disk throughputs even in a dom0, and maybe, also about cpu usage, memory, etc.

certanly installing sar in a domU will give those values, but will this be reliable?

what's your opinion about this?
