This section shows you how to add logs and counters in perfmon in order to measure system performance. You can use these counters to measure and record system activity for a specified duration.

	The screenshots in this section were taken using Windows 2000. The screenshots and steps will vary slightly when using other Windows operating systems.

To start perfmon and add a new counter:

• Click Start > Run. The Run dialog window opens.

• Type perfmon, and click OK.

Starting Perfmon

• In the left pane, expand the Performance Logs and Alerts node.

• Right-click Counter Logs and select New Log Settings.

Choosing New Log Settings

• Enter the name of the new log (e.g. Iguana_Processor), and click OK.

• In the dialog window that appears, click Add.

Adding a New Counter

The Select Counters window appears.

• Under Performance object, choose the system component that you want to measure performance for.

• Then, ensure the Select counters from list option is selected, and choose the counters that you want to measure.

Choosing the Counters to Measure

• After choosing the counters that you want to measure, click the Add button and click Close to exit.

• In the dialog window that appears, click OK. Another dialog window appears, asking you if you want to create a new folder called C:\PerfLogs.

• Click Yes to create the folder.

At this point you can either start the counter manually, or specify a scheduled time for it to run.
