ManagementFactoryjava.lang.management

Java 5.0

This class provides the main entry point into the java.lang.management API. The static factory methods provide a convenient way to obtain instances of the various MXBean interfaces for the currently running Java virtual machine. The returned instances can then be queried to monitor memory usage, class loading, and other details of virtual machine performance.

To obtain an MXBean for a Java virtual machine running in another process, use the newPlatformMXBeanProxy( ) method, specifying a javax.management.MBeanServerConnection as well as the name and type of the desired MXBean. The constant fields of this class define the names of the available beans. Note that the javax.management package is beyond the scope of this quick reference.
