Logging preferences and configuration

Use the logging settings of the Visual Modeler to monitor activity of the Visual Modeler and to help diagnose problems.

The log4j API handles logging and uses the Preferences API to retrieve logging configuration properties. The basic configuration file for the log4j API is log4j.properties. A copy of this file with default logging properties is included in the WEB-INF/lib/cmgt-logging.jar JAR file packaged with the Visual Modeler and is also placed in the WEB-INF/classes/ directory. To override the default properties permanently, you must modify the log4j.properties file. Any values that you specify in this file will overwrite the corresponding values in the log4j.properties file in the cmgt-logging.jar file. You can override the default properties on a transient basis for testing purposes by logging in to the System Administration site of the Visual Modeler as a site administrator and modifying the System Logging properties.
