How can we monitor a Custom IIS Web Module written in .NET

[CommunityUser]

I have the .NET agent installed.  The web module is acting as an caching proxy for resizing images, so the requests are simply image file requests.  The size is embedded into the filename, the module pulls this out, resizes the image, caches it to disk, and rewrites the request to the disk location.  Any help is appreciated.

You need to create a custom entry point (type is .NET Class / Method).
