问题 ENVIRONMENT NetBeans 6.9.1, GlassFish 3.1, METRO 2.1 I want to make a list of available web services, so I'm querying JMX MBeanServer for *:type=WSEndpoint,* . The problem is, there are only ~56 Mbeans after deploy, and WSEndpoint beans are not registered. If I connect with JMXterm, the MBean count jumps up to ~380, and all WSEndpoint beans are visible. From JConsole, I don't see any folder , but after running JMXterm I do. Even if I call the web service, the MBeans stay unregistered. METRO

问题 I have enabled JMX on my tomcat server with -Dcom.sun.management.jmxremote=true -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -Djava.rmi.server.hostname=localhost and I have a spring app that exposes JMX beans with a JmxRemoteLifecycleListener bean: <Listener className="org.apache.catalina.mbeans.JmxRemoteLifecycleListener" rmiRegistryPortPlatform="10000" rmiServerPortPlatform="10001" /> When I run this tomcat instance on virtualbox (using vagrant)

问题 I want to write an unprivileged (non-root-access) JMX client program that monitors a privileged (running as root) application that has JMX local access enabled -Dcom.sun.management.jmxremote . At least on MacOSX, jconsole (and jps) don't see root processes when I run as myself. Is this just the fact of life here, or is there some way to configure this? 回答1: If your client is not permitted to see the root process, then you cannot attach by PID. What you need is to have the root application

问题 how to generate mail alerts for the following changes in jvm 1)memory 2) threads 3)db connections by using jmx any help would be useful thanks 回答1: I'll answer your question re: memory. To get a notification any time a given memory pool exceeds a threshold, do something like the below. To get a list of all the memory pools, call ManagementFactory.getMemoryPoolMXBeans(). Then choose the (ones) that matter for you. One my machine, the list is: Code Cache Eden Space Survivor Space Tenured Gen

问题 I'd like to publish JMX notifications using Spring 3, but would like to avoid using the NotificationPublisherAware interface, since the code is also used by an application that doesn't use Spring. The bean is exposed using MBeanExporter bean. The alternatives I found require registering the mbeans, which I currently do using Spring configuration, so this is a bad option. Is there a way to avoid using the NotificationPublisherAware interface but still publish notifications? 回答1: You don't have

问题 does anybody have some ideas on how to achieve that? Or even a good documentation on how to do that? Basicly everything is done in a test standalone version (by a java client or jconsole I am able to call mbeans methods and everything works fine), but I need to put it in my Tomcat servlet.... Thanks for every suggestions! Rob 回答1: The Tomcat docs on monitoring describe how to enable JMX for Tomcat process's JVM. The short answer is you have to get the com.sun.management.jmxremote.* system

问题 I'm using @EnableMBeanExport in a SpringBoot application to make my beans with @ManagedResource be available to the JMX server. This works fine in simple local processes with VisualVM. I'm now trying to add Jolokia into the mix, so I can reference those beans remotely with a REST service instead of setting up a remote RMI connection, which is annoying. The Jolokia doc page at https://jolokia.org/reference/html/jmx.html says to use the following: MBeanServer jolokiaServer =

问题 I'm trying to use JMX with activeMQ for monitoring so far I've been using this and this as a reference but so far I'm unable to connect to jmx remotely and also I don't see any mention of jmx url in activemq logs. I'm wondering if there is another way to make sure jmx is working? is it supposed to be indicated in activemq logs? PS I'm using jdk1.7 and activeMQ 5.14.2. Thanks in advance! EDIT I set useJmx="true" in my activemq.xml file: <broker xmlns="http://activemq.apache.org/schema/core"

问题 I've gone through the process on this page to expose the JMX interface of a web application. I've managed to view the exposed interface on the Tomcat JMX proxy but when I load JConsole and look for the exposed mbean interface I can't find anything related to the attributes and operations exposed. Thre is no specific entry on jconsole for the web app so I figured it might be under the TOMCAT jmx entry. It's not. (bare in mind, I did manage to see it on the tomcat jmx proxy page). How can I

问题 Whenever a new object is created by my JVM I want to print something in the log. I was trying to detect that using Runtime.getRuntime().freeMemory() but unfortunately it does NOT take into account any short-lived object until it is promoted to the heap (check here for more details). So does anyone know how to detect/track whenever an object is instantiated/created by my JVM? To make it easier, how do we complete the code below: Feel free to use MemoryPoolMXBean and JMX: public class
