Creating a Custom Logging Module

If the logging modules included with IIS do not meet your particular requirements, you can create a custom logging module. For example, you might need to store log information in a format that matches a database table. To do this, you would need to develop a custom logging module to store the data passed from IIS in the appropriate format.

A custom logging module must expose a base set of methods for IIS to use. A module may also support other proprietary methods that are specific to its specialized functions. It is your responsibility to make sure any logging module you create indicates whether it supports a specific method or not. If a method is not supported, your logging module must return an appropriate error code.

If you decide that the logging modules delivered with IIS 4.0 do not meet your requirements, you can create and install a custom logging module.

    To create and install a custom logging module

• Write a COM component that exposes the required methods specified by the ILogPlugin Interface.
• Register the COM component with regsvr32 or another registration tool.
• 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.
