Not able to read heap consumption on application server using a custom JMX code. I am trying to make JMX code read and print current heap memory usage on our application servers. But I can not see which property in the MBeans has this. I am able to read the heap memory stats from Domain controller though. The following code works for Domain controller but not for querying application servers.
JMXConnector jmxConnector = JMXConnectorFactory.connect(serviceURL, map); MBeanServerConnection connection = jmxConnector.getMBeanServerConnection(); ObjectName objectName = ObjectName.getInstance("jboss.as:host=master,core-service=platform-mbean,type=memory"); String attributeName = "heapMemoryUsage"; Object result = connection.getAttribute(objectName, attributeName); System.out.println(attributeName +"="+ result);
Similarly what option should I use to query "heap consumption of each JVM", based on my example to check the server state:
ObjectName objectName = ObjectName.getInstance("jboss.as:management-root=server"); String attributeName = "serverState"; Object result = connection.getAttribute(objectName, attributeName); System.out.println(result);
