WSO2 ESB log is too big, how to set?

Question

I do a performance test on WSO2 ESB. And I found the log is too big that can not open. The biggest file is 7.20GB. I think this is a big problem. I want to set every log file less than 20MB, and I want delete old logs automatic. How to set this? Anyone can help me?

Answer 1

You can configure logging in ESB_HOME/repository/conf/log4j.properties file.

Add following configurations in the log4j.appender.CARBON_LOGFILE=org.apache.log4j.RollingFileAppender section.

log4j.appender.CARBON_LOGFILE.MaxFileSize=20MB
log4j.appender.CARBON_LOGFILE.MaxBackupIndex=1000

So this will ensure total 2MB * 1000 will be used. i. e first 1000 entries of 2MB chunks will be retained

Answer 2

You can configure http_access_log by editing the catalina-server.xml which is located {CARBON_HOME}/repository/conf/tomcat directory and add renameOnRotate in the AccessLogValve

<Valve className="org.apache.catalina.valves.AccessLogValve" directory="${carbon.home}/repository/logs" renameOnRotate="true" prefix="http_access_" suffix=".log pattern="combined" />
