JMX is slightly different on J2SE5 and J2SE6 platforms. We learn JMX Based on J2SE6. JMX is part of the successful Java2 Platform. Its goal is to dynamically manage and monitor resources you are interested in, such as applications, devices, services, and JVMs. JMX supports local and remote access to manage and monitor

The JMX full name is Java Management Extensions, the Java Management extension.

How many times have you ever looked at a running application and asked yourself: "What the hell is it doing?" Why did it take so long? "At these moments, you might think it would be nice if you built more monitoring capabilities in your application." For example, in a server application, you can view the number and type of tasks queued for processing, the tasks currently being processed, throughput statistics in the past minute or hour, average task processing time, and so on. These statistics a

Translated from http://java.sun.com/javase/6/docs/technotes/guides/management/agent.html using JMX to manage your JVMJMX is the acronym for Java Management Extensions and a central part of current Java technology, and JMX makes it easier to build extensible, manageable, scalable Java frameworks. More importantly, JMX is part of the J2SE, which means that using

1. Introduction to JMXWhat is JMX? In an article on the Internet, "JMX (Java Management Extensions) is a framework that embeds management functions for applications. JMX is a set of standard proxies and services. In fact, you can use these proxies and services for management in any Java application.Let's start with what benefits

JMX MBean Basics 1 Introduction This lesson introduces the basic concepts of the JMX API, the managed beans, or mbeans. An Mbean is a managed Java object, somewhat like JavaBean, which follows some design patterns of the JMX specification. A device, an application, or any resource that needs to be managed can be represented as an mbean. An Mbean exposes a managem

The Spring framework minimizes architectural dependencies and materializes the components in the application, but the application is still managed. Fortunately, Spring 1.2 includes advanced JMX integration support, and JMX provides a practical management infrastructure for applications. In this article, Claude Duguay further from Spring JMX, showing you how to tr

This tutorial will provide you with an example of how to build a jmx-usable mina application. The purpose of this tutorial is to help you integrate the JMX technology with the Mina based application.

The article suggests that Ajax and JMX are located on the two opposite sides of the system management stack. However, Ajax models are now ubiquitous in Rich browser clients. This makes the model become blurred in the architecture domain to enhance the support pattern in the problem parsing pipeline. This article describes in detail the advantages of an AJAX architecture-it can "broadcast" administrative status to a user base that can use the browser w
