Using JConsole

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

Specifically, you can use JConsole to perform the following tasks:

• Detect low memory and deadlocks

  JConsole accesses the memory system, memory pools, and MBeans garbage collector to provide information about memory use, including memory consumption, memory pools, and garbage collection statistics.

• Enable or disable garbage collection

• Enable or disable verbose tracing

• Monitor local and remote applications

• Monitor and manage MBeans including current heap memory use, non-heap memory use, and how many objects are pending for finalization

• View information about performance, resource consumption, and server statistics

• View summary information about the JVM and monitored values, threads running on the application, and loaded classes

• View information about operating system resources (Sun’s platform extension), such as:

  • CPU process time

  • How much total and free physical memory is available

  • The amount of committed virtual memory (how much virtual memory is guaranteed to be available to the running process)

  • How much total and free swap space is available

  • The number of open file descriptions (UNIX®only)
