Java Management Extensions (JMX) Tracing








Traces in the JMX implementation are based on the Java SE logging capability (provided by classes in the java.util.logging package). The JMX implementation uses a set of Loggers for sending traces. All Loggers are contained in the javax.management namespace, which corresponds to the name of the root package hosting all public JMX interfaces.

The list below shows the Logger objects used in this implementation and their corresponding category of activity.
