Overview
As an administrator of a Liferay Portal server, you may be required to trace the behaviour of one or more services for a live instance.
This article outlines the steps for enabling or disabling logging categories which typically represent a component or service within Liferay Portal.
The output from the logging system (i.e. Apache Log4j) is typically written to standard output, which is normally routed to the web or app server's log files
e.g.
- LIFERAY_HOME/logs/liferay.log
- LIFERAY_HOME/tomcat-xxx/logs/catalina.out
