Class Overview

This class used to output log statements from within the log4j package.

Log4j components cannot make log4j logging calls. However, it is sometimes useful for the user to learn about what log4j is doing. You can enable log4j internal logging by defining the log4j.configDebug variable.

All log4j internal debug calls go to System.out where as internal error messages are sent to System.err. All internal messages are prepended with the string "log4j: ".

Summary

Constants

public static final String CONFIG_DEBUG_KEY

This constant is deprecated.
Use DEBUG_KEY instead.

Defining this value makes log4j components print log4j-internal debug statements to System.out.

The value of this string is log4j.configDebug.

Note that the search for all option names is case sensitive.

Constant Value: "log4j.configDebug"

public static final String DEBUG_KEY

Defining this value makes log4j print log4j-internal debug statements to System.out.

The value of this string is log4j.debug.

Note that the search for all option names is case sensitive.

Constant Value: "log4j.debug"

Fields
