Change location of the WSO2 Carbon server logs

I'm using WSO2 AM-1.8.0 in this post. Since AM-1.8.0 released in Carbon-4.2.0 same steps apply to all products within this carbon version.

By default all log files are stored in <CARBON_HOME>/repository/logs/ directory.

Lets assume we need to move all these logs to /var/logs/wso2 directory.

1. Open log4j.properties file resides within <CARBON_HOME>/repository/conf/ directory and update following properties as mentioned below.


log4j.appender.SERVICE_APPENDER.File
log4j.appender.TRACE_APPENDER.File
log4j.appender.CARBON_LOGFILE.File
log4j.appender.ERROR_LOGFILE.File
log4j.appender.AUDIT_LOGFILE.File
log4j.appender.ATOMIKOS.File

log4j.appender.SERVICE_APPENDER.File=/var/logs/wso2/${instance.log}/wso2-apigw-service${instance.log}.log
log4j.appender.TRACE_APPENDER.File=/var/logs/wso2/${instance.log}/wso2-apigw-trace${instance.log}.log
log4j.appender.CARBON_LOGFILE.File=/var/logs/wso2/${instance.log}/wso2carbon${instance.log}.log
log4j.appender.ERROR_LOGFILE.File=/var/logs/wso2/${instance.log}/wso2-apigw-errors.log
log4j.appender.AUDIT_LOGFILE.File=/var/logs/wso2/audit.log
log4j.appender.ATOMIKOS.File = /var/logs/wso2/tm.out 

2.  configure HTTP Access log file by changing <CARBON_HOME>/repository/conf/tomcat/catalina-server.xml

<Valve className="org.apache.catalina.valves.AccessLogValve"
directory="/var/logs/wso2"
prefix="localhost_access_log_sample."
suffix=".log"
pattern="%{xxx}i %{xxx}o"
resolveHosts="false"/>

 You may face few hick-ups if you need to move ALL logs from default location.

Eg: - patches.log, wso2carbon-trace-messages.log

At the moment there is no direct way to configure store location for above logs.These properties exist within <CARBON_HOME>/lib/org.wso2.carbon.server-4.2.0.jar and patch applying process take place even before the carbon server start. So we have bundled log4j.properties file within org.wso2.carbon.server-4.2.0.jar.

I will note down a workaround here.

Go to <CARBON_HOME>/lib/ Directory. Open the org.wso2.carbon.server-4.2.0.jar with an archive manager. Open the log4j.properties using a text editor and modify following properties.

log4j.appender.CARBON_LOGFILE.File
log4j.appender.CARBON_TRACE_LOGFILE.File
log4j.appender.CARBON_PATCHES_LOGFILE
