Monitoring and feedback tools for realtime workloads for xen virtual machine

Abstract

In a virtual machine, there is much requirement for supporting realtime characteristic. To support realtime task in a virtual machine, we have to monitor and control resources including CPU, memory, I/O device. Recently several monitor tools are released running on virtual machines including Xenmon. However, it has limitations on supporting detailed information for monitoring realtime workloads. Furthermore, frequent access to trace buffer severely degrades the overall system performance. In this paper, we propose a light-weight monitor tools for Xen virtual machine, which provides workloads monitoring with high accuracy, and users can monitor lots of system information with low overhead. We also provide GUI tools for user friendly purpose.
