Introduction to Performance

provides the following tools for monitoring resource usage on your computer:

System Monitor (part of the Performance Console)

Performance Logs and Alerts (part of the Performance Console)

Task Manager

Monitoring system performance is an important part of maintaining and administering your installation. You use performance data to:

Understand your workload and the corresponding effect on your system's resources.

Observe changes and trends in workloads and resource usage so you can plan for future upgrades.

Test configuration changes or other tuning efforts by monitoring the results.

Diagnose problems and target components or processes for optimization.

System Monitor and Performance Logs and Alerts provide detailed data about the resources used by specific components of the operating system and by programs that have been designed to collect performance data. The graphs provide a display for performance-monitoring data; logs provide recording capabilities for the data. Alerts send notification to users by means of the Messenger service when a counter value reaches, rises above, or falls below a defined threshold.

Microsoft technical support often uses the results of performance monitoring in problem diagnosis. Therefore, Microsoft recommends that you monitor system performance as part of your administrative routine.

Task Manager is another tool that provides performance information about systems running . Task Manager provides information about programs and processes that are running on your computer, plus a summary of its processor and memory usage. For information about Task Manager, see Task Manager Help
