How To get Heap Memory Used

[Tanzy Akhtar]

Hi,
I am using JMX way to get heap memory.
Used the following code to--

    
public class JMXTest {

private static final String DEFAULT_DOMAIN_NAME = "144.120.521.231:9696";

public static void main(String[] args) throws Exception {

		MBeanServer mbs = getMBeanServer();
		System.out.println("------------------------------------");
		JMXServiceURL url = new JMXServiceURL(
				"service:jmx:rmi:///jndi/rmi://144.120.521.231:9696/jmxrmi");
                JMXConnector cntor = JMXConnectorFactory.connect(url);
		MBeanServerConnection connection = cntor.getMBeanServerConnection();
                ObjectName objNameMembers = new ObjectName("java.lang:type=Memory");
		System.out.println("test started : "
				+ connection.getObjectInstance(objNameMembers).getClassName());
}

It's working fine as of now.

But i need to get the value of heapmemory used.
Anybody suugest how to achieve it?

Hi Tanzy,

The object returned is a MemoryMXBean, so cast to it and use its methods.
