SLES 10 and RHEL 5 correct for the virtualization effects and OMEGAMON gives the "normalized" numbers. But the importance of that depends on what you want to know, doesn't it? If you're interested in which Linux process is hogging the guest, the absolute number is irrelevant. It *is* true that for capacity planning and chargeback you need a better absolute number than what older distros provide. As a result, we decided to update OMEGAMON to normalize those numbers for guests that don't generate the more accurate data. We hope to deliver that late this year or early next.
