Writing a Performance Monitor Extension DLL is similar to writing an extension for the Performance Monitor for a Windows-based desktop device.
You can find a simple extension model sample that connects to a device-side server in the C:\Program Files\Common Files\Microsoft Shared\Platman\sdk\wce600\samples\ceperf directory. For more information about the sample, see the Readme.htm file in that directory.
The Performance Monitor Extension Model is identical to the model for Windows-based desktop devices, with the following exceptions:
Registry values
A Performance Monitor Extension DLL uses a different registry value name for the library path to avoid conflicting with existing performance objects for Windows-based desktop devices.
For the Performance Monitor, the CEPERFLIBRARY registry value replaces the LIBRARY registry value for the Performance Monitor for Windows-based desktop devices.
The following example shows how to register a Windows Embedded CE performance object for Performance Monitor.[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\CERasStats\Performance] ... "CEPerfLibrary 600" = "C:\\Projects\\DataViz\\NetMon\\CEPerf\\debug\\cerasstats.dll"PERF types
