This release of J2SE offers significant enhancements for monitoring and management for the Java platform.
Monitoring and management API for the Java virtual machine The new java.lang.management package provides the interface for monitoring and managing the Java virtual machine.
Monitoring and management API for the logging facility The new java.util.logging.LoggingMXBean interface is the management interface for the logging facility.
JMX instrumentation of the Java virtual machine The Java virtual machine (JVM) has built-in instrumentation that enables you to monitor and manage it using JMX. You can easily start a JMX agent for monitoring and managing remote or local Java VMs instrumentation or of any application with JMX instrumentation. See Monitoring and Management Using JMX at http://java.sun.com/j2se/1.5.0/docs/guide/management/agent.html for details.
JavaTM Management Extensions JMXTM API version 1.2 and the RMI connector of the JMX Remote API version 1.0 are included in J2SE 5 release. The JMX API allows you to instrument libraries and applications for monitoring and management. The RMI connector allows this instrumentation to be remotely accessible. For more details, see the JMX documentation at http://java.sun.com/j2se/1.5.0/docs/guide/management/index.html.
