Wiki Page: Is there way to monitor perfmon based application process by PID in Performance Explorer?

If Perfmon has been configured to display the PID, Performance Explorer will display the values in the same way. Perfmon can be configured to display the PID by making a registry change. Making this registry change will display processes in the format of ProcessName_PID instead of ProcessName#1.   Please note, any registry changes are undertaken at your own risk, and a registry backup should be created before making any changes. The registry change can be made as follows: Click START | RUN | type: regedit Locate and then click the following registry subkey: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\PerfProc\Performance On the Edit menu, click New, and then click DWORD Value. Right-click New Value #1, click Rename, and then type ProcessNameFormat to name the new value. Right-click ProcessNameFormat, and then click Modify. In the Data value box, type one of the following values, and then click OK: 1: Disables PID data. This value is the default value. 2: Enables PID data. Exit Registry Editor.
