This is used to capture and log information about the web server. It is further classified into the following three types:

Web server logging

This logging logs information about HTTP transactions using the W3C extended log format. This can be enabled when we need to determine site metrics such as total number of requests being made, or from which IP a request is made, and so on.

Failed request tracing

This logging logs detailed information when the application fails. It contains the complete trace of the web server components used to process the request, and so on.

Detailed error logging

Contains information about the HTTP status codes that indicate a failure. This can be used to determine why the server returned an error code.
