Infinispan Server : How to enable JMX monitoring?

由 隐身守侯 提交于 2019-12-11 03:04:46
问题 I have an Infinispan Server , version 6.0.x, the one derived from JBoss 7.2, and it is working fine for caching. However, when I try to monitor it by JMX I can't. This is URL I type in jconsole.bat : service:jmx:remoting-jmx://MY.IP.ADDRESS.HERE:9999 But I get this error : Exception in thread "VMPanel.connect" java.util.ServiceConfigurationError: javax.management.remote.JMXConnectorProvider: Provider org.jboss.remotingjmx.RemotingConnectorProvider could not be instantiated: java.lang

How to access JMX (Java Beans) from a process running in docker container

由 北慕城南 提交于 2019-12-11 02:57:54
问题 Why is it so hard to connect to a JMX port (using JConsole), when a process is run using Docker. Of course I have exposed the JMX port to the host , and even used Sun specific options while running the Java process (following the instructions from http://ptmccarthy.github.io/2014/07/24/remote-jmx-with-docker/ ). I am able to telnet to the host ip and the exposed JMX port, which tells that it is accessible. But I can't figure out a way to use JConsole and connect to the JMX service running in

Adding metrics to JMX

由 荒凉一梦 提交于 2019-12-11 02:14:56
问题 I have 2 questions regarding JMX: What can you measure in your application using JMX? Is it possible to add metrics to JMX? For instance: seeing how much time a certain operation took. thanks 回答1: You can add whatever metrics you like, you decide what you want to monitor. For the second question, yes you can measure how much time some operation take. One easy to implement your JMX metrics is to use Spring annotations : http://docs.spring.io/spring/docs/3.2.4.RELEASE/spring-framework-reference

JMX client accessible locally only

问题 I want to create a JMX agent that has to be accessible from local host only. Please advise how can I do that. Also help with a Simple JMX client on same machine that will connect to that JMX agent. If somehow we can get away with specifying an explicit port, that will be helpful. 回答1: You might find this helpful. It uses the attach API for Oracle's JVM to connect to a running Java process and have it start a local only JMX agent. You would setup whatever MBeans you want to expose as usual. I

Websphere 7.X. JMX, how to enable all operations in JConsole?

由 随声附和 提交于 2019-12-11 00:06:56
问题 When I open JConsole (using confugured .bat file), inside AppManagement Mbean node I see many operations. But most of them are disabled, enabled only one - "MoveModule" operation.. How to enable all JMX operations under AppManagement Mbean node (like "Install application", redeploy, uninstall etc)? Thanks. 回答1: That is not possible. JConsole allows to invoke methods that only have parameters with simple types. That includes primitive types, wrapper classes for primitive types and strings.

Spring ManagedAttribute appears in the Operations tab of the JMX console

由 百般思念 提交于 2019-12-10 22:55:13
问题 My MBeans are annotated using Spring annotations as follows: @ManagedAttribute(description = "returns the name") public String getName() { return name; } Now, whenever I open a JMX Console (be it VisualVM or JConsole), I can see the attributes of my beans in the Attributes tab, but I can also see the getName() method exposed in the Operations tab. Is there a way in which I can only see the attribute in the Attribute tab (i.e. hide it from the Operations tab)? 回答1:
