Creating a Custom Logging Module

A custom logging module must expose a base set of methods for IIS to use. These methods are defined in the ILogPlugin or ILogPluginEx interfaces. Your module may also support other proprietary methods that are specific to its specialized functions.

Note   Just as with any COM-compliant component, it is your responsibility to make sure any logging module you create indicates whether it supports a specific method or not, using the standard COM QueryInterface mechanism. If a method is not supported, your logging module must return an appropriate COM error code.

To create and install a custom logging module

• Write a COM component that exposes the required methods specified by the ILogPlugin or ILogPluginEx interface definitions.
• Register the COM component with Regsvr32.exe.
• Add your logging module to the list of available logging modules by adding a key in the /LM/LOGGING path of the metabase.
• Establish the logging module for a particular Web site either by using the Administrative user interface or by using a script.
• If you wish to provide a user interface for your custom logging module, see Creating a Logging User Interface Module.
