jmx

问题 I have a Java program providing services which can be invoked by calling methods on an JMX MBean via RMI. The service is running without problems, but I am facing the question of how to shut down the service without interrupting a potential new concurrent request to the service. One solution for this problem would be to wait for all JMX connections to be closed and only then (and when there is no more background activity) to shut down the process. JMXConnectorServer has a method

问题 Is it possible to create a JMX client that doesn't run on the JVM? From my understanding JMX is a protocol on top of other protocols (like RMI) so it should be possible to create a C or Go client. Any reason why this hasn't been done? I am aware of Jolokia and realise it can be used as a proxy. 来源： https://stackoverflow.com/questions/49207999/non-java-jmx-client

问题 This is a follow-up of How to stop message processing before undeploying? I want to configure a JMX Notification Listener for undeployment events, but I don't know how to set the mbean name correctly. We are currently using JBoss 4.2.3. The following attempt won't trigger any notification. <mbean code="jboss.example.NotificationListener" name="jboss.example:name=NotificationListener"> <attribute name="SubscriptionList"> <subscription-list> <mbean name="jboss.j2ee:service=EjbModule,type=jmx

问题 I am trying to create a jmeter jmx file using the jmeter java api. This is what I have done, gui.jmx Use the jmeter gui application to create a reference jmx file against which I can compare. To the test plan, I only add a thread group and a java sampler within the thread group. All values are default. code.jmx Using the jmeter java api, I create a jmx file containing a test plan, thread group and java sampler. All values are set as per the case 1. After creating the jmx file from code, I

问题 So when I try to connect to jmx from jconsole I get this exception: Caused by: java.rmi.ConnectException: Connection refused to host: 78.84.17.116; nested exception is: java.net.ConnectException: Connection timed out: connect at sun.rmi.transport.tcp.TCPEndpoint.newSocket(TCPEndpoint.java:601) at sun.rmi.transport.tcp.TCPChannel.createConnection(TCPChannel.java:198) ... I was trying to connect to such url in jconsole: service:jmx:rmi:///jndi/rmi://78.84.17.116:43030/test My jmx spring

问题 we're currently in the process of porting some of our projects from JBoss 4.x to JBoss 7. So far everything seems to work fine, except for our MBeans, which we're commonly using to provide simple management operations. I've been searching for quite a while now, but either I'm incapable of comming up with the correct search term or I'm missing some piece of knowledge to bridge the gap between MBean definition in JBoss 4.x and JBoss 7. Thus, hopefully someone can provide a hint on what I might

问题 The ThreadMXBean has two methods for retrieving thread time usage: getThreadUserTime getThreadCpuTime What is the difference between the two? Update 2 : If I'm able to link to the javadocs, please don't quote them - I've read them already. Update : here's some code which I tried to use to learn what these times mean, with little success: ThreadMXBean threadMXBean = ManagementFactory.getThreadMXBean(); threadMXBean.setThreadContentionMonitoringEnabled(true); long mainThreadId = getMainThreadId

问题 For some integration projects I would like to query JMX agents from non-Java clients. I found two options so far, ws-jmx-connector (Soap based) and mx4j and its JMX HTTP adaptor which returns XML document responses. The JSR 262 based ws-jmx-connector seems to be no longer in active development. I have not tried MX4J so I do not know if it is possible to use the HTTP adaptor with the standard JMX implementation in the J2SE. Are there other software projects which can help to connect non-Java

问题 I can see that some methods on the jconsole are disabled. Given below is the screenshot for com.sun.management.ThreadMXBean The javadocs for these MBean methods do not specify anything about the accessibility part. I think it is a security feature, but I am not able to get a concrete answer for this. The obvious second part to this question is how to create custom MBean implementations which can be selectively disabled on the jconsole. Given below is the system config : JConsole version "1.7
