Pree,
If you check back in the xen-devel archives, you'll find around late
August I sent out a package called xenmon, which provides fairly
fine-grained reporting of various metrics, including cpu utilization for
each domain, and cumulative data over 1 second and 10 seconds. This tool
can show some of what you are interested in. I am planning another
release of xenmon "real soon now" that incorporates some improvements
and bug fixes.
