Metis: a profiling toolkit based on the virtualization of hardware performance counters
With wide application of virtualization technology, the demand is increasing for performance analysis and system diagnosis in virtualization environment. There are some profiling toolkits based on hardware events, such as OProfile in native Linux and Xenoprof in Xen virtual machine environment. However, sometimes users in different domains need monitor different hardware events individually at the same time. For programming and profiling in environment for virtual machine, it may become popular in the coming future. In this paper, we present Metis, a system-wide profiling toolkit for Xen virtual machine environment based on the virtualization of hardware performance counters.
