Abstract

Since the shortage of the CPU monitoring tools for Xen-based environment,a specialized CPU monitoring tool named XCPUMon is proposed.It provides monitoring information referring to CPU,including both Physical CPU(PCPU) and Virual CPU(VCPU),such as the utilization of CPU,blocked time of CPU as well as waiting time of CPU.This paper describes the algorithm of estimating CPU utilization rate in details.The result of the experiment shows that XCPUMon can provide detailed and accurate CPU information.
