Debugging with JConsole

The Java Monitoring and Management Console (JConsole) is a Java Management Extension (JMX) technology-compliant graphical management tool bundled with JDK 5 (and later). JConsole connects to a running JVM and gathers information from the JVM MBeans in the connected JMX agent.

For example, you can use JConsole to

• Detect low memory

• Enable or disable garbage collection

• Enable or disable verbose tracing

• Detect deadlocks

• Control Waveset log levels

• Access information about operating systems resources (Oracle’s platform extension)

• Monitor and manage MBeans

• View information about the JVM and monitored values, threads running on the application, and class loading
