Java Management Extensions (JMX)
The Java Management Extensions (JMX) API is a standard API for
management and monitoring of resources such as applications,
devices, services, and the Java virtual machine. The JMX technology
was originally developed through the Java Community Process (JCP)
as Java Specification Request (JSR) 3, Java Management Extensions,
and JSR 160, JMX Remote API. The Java Platform, Standard Edition
version 7, contains JMX version 2.0, which merges the JMX and JMX
Remote API technologies into a single version. JMX 2.0 was defined
by JSR 255.
Typical uses of the JMX technology include:
- Consulting and changing application configuration
- Accumulating statistics about application behavior and making
them available
- Notifying of state changes and erroneous conditions.
The JMX API includes remote access, so a remote management
program can interact with a running application for these
purposes.

overview provides an introduction to the JMX technology.
API Specification

Tutorials and Programming Guides
- JMX
Tutorial - This tutorial presents some examples of the features
of the JMX technology.
- Examples - The JMX reference
implementation contains code examples for different areas of JMX
operation.
In addition to the above examples, once you have installed the
Java Development Kit (JDK) 6, a sample application that
demonstrates a real-life implementation of the JMX API can be found
in the following directory:
JDK_HOME/sample/jmx/jmx-scandir
In the path above, JDK_HOME is the directory
in which the JDK software is installed. The
jmx-scandir example is an advanced example, which
presents advanced concepts of the JMX API in a real-world
scenario.
