DGMonitor: A Performance Monitoring Tool for Sandbox-Based Desktop Grid Platforms

Accurate, continuous resource monitoring and profiling are critical for enabling performance tuning and scheduling optimization. In desktop grid systems that employ sandboxing, these issues are challenging because subjobs in-side sandboxes are executed in a virtual computing environment and the state of the virtual computing environment within the sandboxes is reset to empty after each sub-job completes. DGMonitor is a monitoring tool which builds a global, accurate, and continuous view of real resource utilization for desktop grids with sandboxing. The monitoring tool measures performance unobtrusively and reliably, uses a simple performance data model, and is easy to use.
