Virtual machines are commonly used in commercially-significant systems, for example, Sun Microsystems' Java and Microsoft's .NET. The virtual machine offers many advantages to the system designer and administrator, but complicates the task of workload characterization: it presents an extra abstraction layer between the application and observed hardware effects. Understanding the behavior of the virtual machine is therefore important for all levels of the system architecture. The author has constructed a tool which examines the state of a Sun Java HotSpot virtual machine running inside Virutech's Simics execution-driven simulator. One can obtain detailed information about the virtual machine and application without disturbing the state of the simulation.
