Mule log4j.properties 설정 위치

$MULE_HOME/conf/log4j.properties 여기다가 만들면 된다.


This directory is used for tracing the execution of the Mule container.

Top-level logger for the Mule container is configured in "$MULE_HOME/conf/log4j.properties" or

"$MULE_HOME/conf/log4j.xml".

*** Xml format has higher priority and will be used if found or in presence of both xml and properties configs. ***

Log4j xml docs: http://wiki.apache.org/logging-log4j/Log4jXmlFormat

Container-level logging is written to the $MULE_HOME/logs/mule.log file.

Application-level logging supports 2 modes:

    1. No log4j configuration packaged with the app (either in app's lib or classes) -

       a rolling log file is automatically created by Mule:


              $MULE_HOME/logs/mule-app-<appName>.log


       The format is the same as the default Mule config.


    2. A log4j configuration is packaged with the app - no default log file is created

       by Mule and app has a full control (and responsibility) to configure logging.


*** TIP: use ${mule.home} placeholder in log4j.properties to resolve the Mule's directory (e.g. for file appenders). ***

In addition to the application's output, the wrapper also sends any JVM-level or 

OS-level errors/warnings to the log file.  This means that if the JVM crashes 

and automatically restarts (enabled by default), the time and cause of the crash 

will remain in the log file after the JVM restarts.
