Goal

Classical performance monitoring tools like Sar, OSWatcher essentially provides historical data from Dom0, *not* for hypervisor. Similarly, while Oracle VM Manager UI (3.2.x and above) provides live monitoring capablities using graphs and charts, it cannot be captured for further analysis. So, if historical stats (CPU/Memory/Disk/Network) from all Guests running on the hypervisor is needed, consider running xentop in batch mode (-b) and dump it to a text file. This document explains a use case of xentop to capture stats of all VM's for capacity planning and analyzing trends.
