JMX Programming Model

JMX Programming Model


Instrument your applications, services, or devices for manageability is much simple when JMX used.

A D V E R T I S E M E N T
JMX technology shares Java's object model. If you are already familiar with Java and JavaBeans component model, you know 95% of all you need to know.




Basic Application

This basic application manages a resource which create a simple standard MBean that exposes a String object and an operation.

First of all to develop the MBean interface. This application consist interface called HelloMBean, which declares three methods: one getter, one setter, and one for saying hello as shown in Code Example 1.

Example 1: HelloMBean.java

public interface HelloMBean {

public void setMessage(String message);

public String getMessage();

public void sayHello();
}


Next step is to apply the MBean interface. A example is shown in the following code.




Example 2: Hello.java

public class Hello implements HelloMBean {
private String message = null;

public Hello() {
message = "Hello there";
}

public Hello(String message) {
this.message = message;
}

public void setMessage(String message) {
this.message = message;
}

public String getMessage() {
return message;
}

public void sayHello() {
System.out.println(message);
}
}


By this way your first MBean created. The next step is to test the MBean, by developing a JMX agent in which you register the MBean. A JMX agent acts as a container for the MBean and it is a component in the agent level. A sample agent, SimpleAgent, is provided in Example 3. This agent performs the following tasks:

  1. Gets the platform MBeanServer
  2. Registers an instance of the Hello MBean



Example 3: SimpleAgent.java

import javax.management.*;
import java.lang.management.*;

public class SimpleAgent {
private MBeanServer mbs = null;

public SimpleAgent() {

// Get the platform MBeanServer
mbs = ManagementFactory.getPlatformMBeanServer();

// Unique identification of MBeans
Hello helloBean = new Hello();
ObjectName helloName = null;

try {
// Uniquely identify the MBeans and register them with the platform MBeanServer
helloName = new ObjectName("SimpleAgent:name=hellothere");
mbs.registerMBean(helloBean, helloName);
} catch(Exception e) {
e.printStackTrace();
}
}

// Utility method: so that the application continues to run
private static void waitForEnterPressed() {
try {
System.out.println("Press to continue...");
System.in.read();
} catch (Exception e) {
e.printStackTrace();
}
}

public static void main(String argv[]) {
SimpleAgent agent = new SimpleAgent();
System.out.println("SimpleAgent is running...");
SimpleAgent.waitForEnterPressed();
}
}




The java.lang.management.ManagementFactory class is a factory class for getting managed beans for the Java platform. In this example, the getPlatformMBeanServer() method is used to get the platform MBeanServer, which is the interface for MBean manipulation on the agent side. It contains the methods necessary for the registration, creation and deletion of MBeans. The MBeanServer is the core component of the JMX agent infrastructure.

To test with this application follow this step:

  1. Create a directory of your choice (such as jmx-example)
  2. Copy Code Samples 1, 2, and 3 into that directory
  3. By using javac compile the .java extension file
  4. Execute SimpleAgent. In order to use the jconsole tool to manage it, you should run the SimpleAgent as follows:

        prompt> java -Dcom.sun.management.jmxremote SimpleAgent

    Note: The -Dcom.sun.management.jmxremote system property creates an RMI connector to the platform MBeanServer.



  5. By using the jconsole tool connect to the JMX agent. Execute the jconsole tool from the command line. Once you start jconsole, it will display the list of local processes to be monitored as shown in Figure 2.

Figure 2: The jconsole monitoring tool



6.  Now, you can connect to the service. Once connected, select the MBeans tab so that you can list the MBeans and manage them as shown in Figure 3.


Figure 3: The MBeans tab of jconsole

Note that local monitoring with jconsole is useful for development and prototyping. But it is not recommended that jconsole be used locally for production environments as it consumes significant system resources. jconsole should be used on a remote system from the platform being monitored.
