The ManagementFactory class is a factory class for getting managed beans for the Java platform. This class consists of static methods each of which returns one or more platform MXBeans representing the management interface of a component of the Java virtual machine.

Platform MXBeans

A platform MXBean is a managed bean that conforms to the JMX Instrumentation Specification and only uses a set of basic data types. A JMX management application and the platform MBeanServer can interoperate without requiring classes for MXBean specific data types. The data types being transmitted between the JMX connector server and the connector client are open types and this allows interoperation across versions. See the specification of MXBeans for details.

Each platform MXBean is a PlatformManagedObject and it has a unique ObjectName for registration in the platform MBeanServer as returned by by the getObjectName method.

An application can access a platform MXBean in the following ways:

1. Direct access to an MXBean interface

Get an MXBean instance by calling the getPlatformMXBean or getPlatformMXBeans method and access the MXBean locally in the running virtual machine.

Construct an MXBean proxy instance that forwards the method calls to a given MBeanServer by calling the getPlatformMXBean(MBeanServerConnection, Class) or getPlatformMXBeans(MBeanServerConnection, Class) method. The newPlatformMXBeanProxy method can also be used to construct an MXBean proxy instance of a given ObjectName. A proxy is typically constructed to remotely access an MXBean of another running virtual machine.

2. Indirect access to an MXBean interface via MBeanServer

Go through the platform MBeanServer to access MXBeans locally or a specific MBeanServerConnection to access MXBeans remotely. The attributes and operations of an MXBean use only JMX open types which include basic data types, CompositeData, and TabularData defined in OpenType. The mapping is specified in the MXBean specification for details.

The getPlatformManagementInterfaces method returns all management interfaces supported in the Java virtual machine including the standard management interfaces listed in the tables below as well as the management interfaces extended by the JDK implementation.

A Java virtual machine has a single instance of the following management interfaces:

Management Interface ObjectName

ClassLoadingMXBean java.lang:type=ClassLoading

MemoryMXBean java.lang:type=Memory

ThreadMXBean java.lang:type=Threading

RuntimeMXBean java.lang:type=Runtime

OperatingSystemMXBean java.lang:type=OperatingSystem

PlatformLoggingMXBean java.util.logging:type=Logging

Management Interface	ObjectName
`ClassLoadingMXBean`	`java.lang:type=ClassLoading`
`MemoryMXBean`	`java.lang:type=Memory`
`ThreadMXBean`	`java.lang:type=Threading`
`RuntimeMXBean`	`java.lang:type=Runtime`
`OperatingSystemMXBean`	`java.lang:type=OperatingSystem`
`PlatformLoggingMXBean`	`java.util.logging:type=Logging`

A Java virtual machine has zero or a single instance of the following management interfaces.

Management Interface ObjectName

CompilationMXBean java.lang:type=Compilation

Management Interface	ObjectName
`CompilationMXBean`	`java.lang:type=Compilation`

A Java virtual machine may have one or more instances of the following management interfaces.

Management Interface ObjectName

GarbageCollectorMXBean java.lang:type=GarbageCollector,name=collector's name

MemoryManagerMXBean java.lang:type=MemoryManager,name=manager's name

MemoryPoolMXBean java.lang:type=MemoryPool,name=pool's name

BufferPoolMXBean java.nio:type=BufferPool,name=pool name

Management Interface	ObjectName
`GarbageCollectorMXBean`	`java.lang:type=GarbageCollector,name=`collector's name
`MemoryManagerMXBean`	`java.lang:type=MemoryManager,name=`manager's name
`MemoryPoolMXBean`	`java.lang:type=MemoryPool,name=`pool's name
`BufferPoolMXBean`	`java.nio:type=BufferPool,name=`pool name
