Part II Java Management Extensions (JMX) Technology Tutorial. 9 Getting Started .. and in the PDF specification documents for each JSR. As its name. Learn how to create and manage an MBean with a quick intro to JMX (Java Management Extensions). The MBean Explorer lists all the domains, MBeans, attributes, and operations inside a connection. When you double-click an MBean in the MBean Explorer.

It provides an architecture to manage resources dynamically at runtime. JMX is used mostly in enterprise applications to make the system configurable or to get the state of application at any point of time. MBean server works as a management agent for all the MBeans registered. Lets start now…. First of all we need to create MBean and for that we need to first create the interface that defines the attributes and operations that we want to expose.

MBean server works as a management agent for all the MBeans registered. Lets start now…. First of all we need to create MBean and for that we need to first create the interface that defines the attributes and operations that we want to expose. The interface name must end with MBean. If you just want to allow read-only, you can leave setter methods.

Next step is to provide the actual implementation of the MBean interface. So my implementation class will be SystemConfig.

Now we need to register our MBean implementation to the MBean server. We can keep any name of our class. After registering MBean, I will keep the thread running until we modify the thread count to 0 through jconsole, that will be the logic to end our application. When I run the above program, it registers our MBean implementation to the platform MBean server and keeps on printing following lines on console. To start JConsole, all you need to do is open a terminal window and run jconsole command.

JConsole allows to create local connection as well as connection to remote processes, you will be able to see our program name in the list of local processes. Just chose the application and click on Connect button, once connected go to MBean tab and you will see that we can change the value of threadCount and schemaName dynamically and any value changed there will be reflected in console where our application is running.

We are also presented with the methods that we can invoke. As soon as you will change the threadCount to 0, the application will exit the do-while loop and terminate.

If you have come this far, it means that you liked what you are reading. Why not reach little more and connect with me directly on Facebook or Twitter. I would love to hear your thoughts and opinions on my articles directly. Recently I started creating video tutorials too, so do check out my videos on YouTube. I have one question 1.

What is Jconsole role here, is it agent or monitor? Who is acting as a MBean server?

Monitoring Server Resources Using the JMX Console

If I run this on STS. Wonderful description about JMX.

It gave clear picture what JMX is and how we can use it. Looking forward to read your other articles: NdsPlatform has identified runtime environment as JUnit. MBean class com. Class com.

Excelent post! I had no idea what JMX was…but now I know what it is in 5 minutes!!! Thanks a lot Mr. Hi Pankaj, Great tutorial! One thing you might add as a Windows tidbit…If your MBean server application runs as Administrator, then you also need to run JConsole as Administrator. JMX gives developers a standard and simple way to manage resources, including services, devices, and applications. It is dynamic, making it possible to manage and monitor resources as soon as they are created, implemented or installed.

These are registered on the mBean server, a core-managed object server that acts as an agent and can be used on a majority of devices that support Java.

In simpler terms, mBeans acts like Java wrappers for services, components, devices, or applications in a distributed network, while the mBean server provides the actual management, as it is where you would find all the manageable resources. This server then becomes the central focus of the architectural frame, which allows server components to plug in and find manageable objects.

This means that the resources are independent and apart from the management infrastructure, and these resources are manageable no matter how the management applications are deployed.

These connectors allow you to access the agents from your remote management applications. These connectors may use different protocols and still work with the same management interface. On the other hand, a management application can easily manage the resources, no matter what communication protocol is used.

In fact, it is possible to use JMX agents with systems and applications that are not compatible with the JMX specifications, as long as these applications support JMX agents.

There are many reasons why you should use Java Management Extensions technology — as it provides you with a flexible way to create Java applications.

All your application needs to have is the managed object server, and as long as the mBeans are registered in the object server, you can use its functionality. You now have a standard means to manage your Java systems, networks and applications.

You can also use it to manage JVMs. You can initiate a JMX agent to gain access to the instrumentation found in a JVM, at which point you can now remotely monitor or manage a Java virtual machine.

You now have a dynamic and scalable management architecture. Each JMX agent service can be used with the management agent. This modularity means that the technologies can scale and can be used with smaller devices to huge telecommunication systems. Just as long as you have the core services identified by the specification, you can add services and load, unload, and update these dynamically.

JMX uses standard Java technology and will use current Java specifications.

This would help you cut down on costs in developing JMX apps.
