)

Parameters

appenderName

A unique name to use for this appender for reference later.

fileName

The full or relative path to the file to create or use for logging. If one exists, it will be appended to.

This will create an initialize the appender. Nothing will be written to the file until this appender is associated with the root logger or any loggers in the hierarchy. See the AddAppenderToRoot and AddAppenderToLogger methods for more information on how to do this association.

NOTE: After you are finished configuring LogManager, you must call Reconfigure in order for the changes to fully take effect.
