Performance Counter CustomActions

The PerfCounter element allows you to register your performance counters with the Windows API. There are several pieces that all work together to successfully register:

• Your performance DLL - The DLL must export Open, Collect, and Close methods. See MSDN for more detail.
• Performance registry values - The registry must contain keys pointing to your DLL and its Open, Collect, and Close methods. These are created using the Registry element.
• Perfmon INI and H text files - These contain the text descriptions to display in the UI. See MSDN for lodctr documentation. This MSDN documentation is a good place to start. See below for samples re-purposed from MSDN.
• The RegisterPerfmon custom action - You can link with sca.wixlib to ensure that the custom actions are included in your final MSI. See server custom action documentation. The custom action calls (Un)LoadPerfCounterTextStrings to register your counters with Windows’ Perfmon API. To invoke the custom action, you create a PerfCounter element nested within the File element for the Perfmon.INI file. The PerfCounter element contains a single attribute: Name. The Name attribute should match the name in the Registry and in the .INI file. See below for sample WIX usage of the <PerfCounter> element.
