Configuring Log4j2

NOTE:  The following applies only to WOW 7.8 and above which use Log4j2 instead of log4j.  

A configuration file called log4j2.properties is located at <tomcat>/wowxx/web-inf/classes folder.  This file holds all the properties to control the log4j2 logging behavior.  Examine this file and review the comments which are preceded by the # character.   You may adjust the logging level, output file name, and other behavior.  It is recommended to backup this file prior to editing.  The most common task is to adjust the logging level.  The possible logging levels are: DEBUG, INFO, WARN, ERROR, FATAL, OFF.    DEBUG will give the most verbose messages while FATAL only logs critical events.  To adjust logging level, fine the following line towards the bottom of the file:  

rootLogger=WARN,LOGFILE,CONSOLE,WOWLogAppender     

Change "WARN" to your desired logging level such as INFO, ERROR, DEBUG, etc.  You must restart Tomcat for your change to become effective.
