Logging Properties

This chapter describes how to change the way Java Mission Control logs errors and warnings.

By default, the JMC client uses the logging.properties file located in the com.jrockit.mc.rcp.application package (Java Archive or JAR file) to control the way that logging is performed. For example, if you have a commercial license of the JDK installed in JAVA_HOME, the location of this JAR file should be JAVA_HOME/lib/missioncontrol/plugins.

In JMC 5.5, you can use a system property to specify the logging configuration file. Either start JMC with jmc -vmargs -Djava.util.logging.config.file=<the logging file to use>, or update the -vmargs section of the jmc.ini file, adding a line that says -Djava.util.logging.config.file=<the logging file to use>.

You can also switch to debug logging by simply starting JMC with jmc -debug.
