Re: [Xen-users] Measuring overall CPU utlization
I notice that the xentop and xenmon tools do not try to combine the CPU usage of an unpriveliged domain with the CPU usage done by dom0 on its behalf for IO. Has any work been done for determining the "total" CPU usage of each unpriveliged domain? For example, I may have an application running on a VM which is very IO intensive. As a result, its CPU allocation may be very low, but dom0 will be doing quite a bit of work on its behalf. Presumably this could be estimated to some degree by looking at the number of IO exchanges as reported by xenmon, but it seems like there should be a more precise way.
any suggestions or pointers?
thanks
-Tim

That looks like it's working. Thanks! - John
