Using JConsole to Monitor Applications
The article describes how JConsole can be used to observe information about an application running on the Java platform. The article first gives an overview of the J2SE 5.0 monitoring and management architecture and how JConsole plugs into the architecture. It then describes how to use JConsole to access several core monitoring and management functionalities provided by the Java platform including:
Detect low memory
Enable or disable GC and class loading verbose tracing
Detect deadlocks
Control the log level of any loggers in an application
Access OS resources—Sun's platform extension
Manage an application's Managed Beans (MBeans)
