Windows Performance Monitor

Windows Performance Monitor to examine how programs you run affect your computer’s performance, both in real time and by collecting log data for later analysis.

Windows Performance Monitor uses performance counters, event trace data, and configuration information, which can be combined into Data Collector Sets.

Performance counters are measurements of system state or activity. They can be included in the operating system or can be part of individual applications. Windows Performance Monitor requests the current value of performance counters at specified time intervals.

Event trace data is collected from trace providers, which are components of the operating system or of individual applications that report actions or events. Output from multiple trace providers can be combined into a trace session .

Configuration information is collected from key values in the Windows registry. Windows Performance Monitor can record the value of a registry key at a specified time or interval as part of a log file.

In Windows Performance Monitor, expand Reports and click User Defined or System .

2.

Additional considerations

• To open Windows Performance Monitor, click Start , click in the Start Search box, type perfmon , and then press ENTER.

• Another way to view the most recent report for a Data Collector Set is to expand Data Collector Sets , expand User Defined or System , click the name of the Data Collector Set in the navigation pane, and click the View Latest Report icon in the toolbar.

• You can also create a new report for a data collector set by typing perfmon /report “Data_Collector_Set_name” at a command prompt. Typing perfmon /report without any other parameters will generate the System Diagnostics report.

• If a Data Collector Set has not run, no reports will be available for it.

• If a Data Collector Set is currently running, the console pane will display information about how long it is configured to run.

• After data collection has stopped, there will be a delay while the report is generated. During this time, the console pane will display a working icon.

• Larger log files result in longer report generation times. If you review your logs frequently to see recent data, we recommend that you use limits to automatically segment your logs. You can use the relog command to segment long log files or combine multiple short log files.

• For more information about the relog command, type relog /? at a command prompt.
