Note Performance Monitor is a Windows NT administrative tool that monitors performance on both local and remote computers. Performance Monitor was replaced by the Performance console in Windows 2000. However, Performance Monitor can still be used to capture performance data from a Windows 2000-based computer, and therefore it is included in the Windows 2000 Resource Kit.
