Configuring Logging for Studio

About logging in Studio
Studio uses the Apache log4j logging utility.

About the log4j configuration XML files
The primary log configuration is managed in portal-log4j.xml, which is packed inside the portal application file WEB-INF/lib/portal-impl.jar.

About the Studio log files
For Studio, one log file contains all of the log messages, and a second file is used only for metrics logging.

Using the Control Panel to adjust logging verbosity
For debugging purposes in a development environment, you can use the Control Panel to dynamically adjust logging verbosity levels for any class hierarchy.

How log4j.properties is used in Studio
In Studio, a log4j.properties configuration file is used to start up the Tomcat bundle. Otherwise, all log4j configuration comes from the XML configuration files.
