Click on Start, then click on Run, type in Perfmon and click OK. Expand Data Collector Sets, right click on User Defined, select New, then select Data Collector Set. Type in a name, for example mycollectorset1, then click the create manually (Advanced) radio button, then click the Next button.
Make sure that Create data logs is selected, and check the Performance counter checkbox, then click Next button.
Click the Add button, and find the counters in the list that you want to keep track of. I want to keep track of Memory and Process. So find Memory in the list, expand it, click on it to select everything under it, then click the Add » button. Now find Process in the list, expand it, click on it to select everything under it, then click the Add » button. Then click the OK button when you are done adding counters. Now click Next button.
If you want, you can click the Browse button to change where the datacollectorset will be stored...I just leave the default inside %systemdrive%\PerfLogs\Admin\mycollectorset1. Then click Next button, and then click Finish button.
Expand Data Collector Sets, and find your new collector set in the list, right click on it, and select Start. And now it will say Running. Leave it run for awhile so it can collect data about the counters. Then to stop it, right click on the collector set, and select Stop.
Go to the directory where the collector set was saved, for example %systemdrive%\PerfLogs\Admin\mycollectorset1 and double click on the mycollectorset1.blg file. Then click on each one of the properties of the counters, for example Page Faults/sec, and it will tell the Average, Minimum, and Maximum values for each counter property.
