Performance Monitor is a Windows graphical tool for measuring the performance of your own computer or other computers on a network. On each computer, you can view the behavior of objects such as processors, memory, cache, threads, and processes. Each of these objects has an associated set of counters that provide information on such things as device usage, queue lengths, and delays, as well as information used for throughput and internal congestion measurements.

It provides charting, alerting, and reporting capabilities that reflect current activity along with ongoing logging. You can also open log files at a later time for browsing and charting as if they were reflecting current activity. To monitor performance on Windows, see the operating system documentation.
