jmx

问题 I'm using a fresh ActiveMQ 5.10.0 installation, where I have a message in a queue called 'testing'. I also replaced the ACTIVEMQ_SUNJMX line in bin/activemq to enable JMX: ACTIVEMQ_SUNJMX_START="-Dcom.sun.management.jmxremote.port=1099 -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false" JMXServiceURL url1 = new JMXServiceURL("service:jmx:rmi:///jndi/rmi://10.222.222.222:1099/jmxrmi"); JMXConnector jmxc = JMXConnectorFactory.connect(url1);

问题 activemq : apache-activemq-5.14.0 jconsole using jdk1.7 I have started the activemq which comes with the jetty server. Minor change to make the jmx enable is by making change in activemq.xml managementContext createConnector="true" --- default is false when i start i am seeing the message JMX consoles can connect to service:jmx:rmi:///jndi/rmi://localhost:1099/jmxrmi So I start Jconsole use remote process and use service:jmx:rmi:///jndi/rmi://localhost:1099/jmxrmi with no password : it says

问题 I need to create a container level JMX MBean for tomcat servers to allow enterprise level monitoring of a few custom features. The examples I am finding online are focused on webapp level MBeans. I found a few examples for Tomcat 5, but it looks like a lot has changed since then. How can I register an MBean for an entire Tomcat instance? 回答1: Tomcat already have MBeans for monitoring stuff. You need to enable it via CATALINA_OPTS, just add: -Dcom.sun.management.jmxremote -Dcom.sun.management

问题 I am running tomcat with a jacoco agent like this: -javaagent:/path_to_jar/jacocoagent.jar=jmx=true,output=tcpclient,port=8001 which I know is working because lsof command lists 88208 TCP localhost:**8001** (LISTEN) . When I run this example code with PORT = 8001; I get the error: Exception in thread "main" java.net.SocketException: Connection reset This appears to be an older example from jacoco. Has something changed with that way I need to access the tcp server? I have also tried to access

问题 I need to add a JMXMP listener to an existing Java application without changing any code. The classic RMI based protocol doesn't work in the target environment do to firewall restrictions. In other words: I would like to access the JMX of the process just by adding the jmx_remote-optional to the classpath and some env properties analog to com.sun.management.jmxremote for the RMI connector. I couldn't find anything in the various docs out there - I managed to use JMXMP in the target env with

问题 I was going through the Spring documentation on JMX and came across the following paragraph: By configuring NotificationListeners in place, every time a JMX Notification is broadcast from the target MBean (bean:name=testBean1),the ConsoleLoggingNotificationListener bean that was registered as a listener via the notificationListenerMappings property will be notified. And this is how the ConsoleLoggingNotificationListener is implemented: public class ConsoleLoggingNotificationListener

问题 I am using the ActiveMQ extension of AppDynamics. It is good to start. With JMXRemote(enabled in artemis.profile) it is OK. But, I want it from localhost. JMX is enabled by default for localhost for AMQ. AMQ management console use jmx internally and it works without JMXRemote enabled. What service URL jolokia use internally to connect using JMX from localhost? I have tryed with following URL: serviceUrl: "service:jmx:rmi:///jndi/rmi://:1099/jmxrmi" 回答1: The first step is to add a username and

问题 We have a "Kerberized Kafka cluster" running brokers version Apache Kafka 0.11.This cluster is managed by a different team and we dont have any control over this. We are now trying to install Kafka Connect cluster on our own K8S cluster. We were following this compatibility matrix https://docs.confluent.io/current/installation/versions-interoperability.html According to this, we had to stick with Confluent Platform 3.3.3 images for Schema Registry and Kafka Connect pods since the Brokers

问题 I cannot connect to a remote VM using Java Mission Control . I can connect using VisualVM with relative ease. The reason I want to use Mission Control is due to a long-standing bug with VisualVM having to be restarted whenever the remote VM is restarted. Therefore, most of the leg-work involved in remote JMX connections is already in-place. I have already enhanced the configuration for Mission Control as instructed here: https://technology.first8.nl/using-mission-controle-for-remote-profiling

问题 I wrote an program to trace the performance of an application using AspectJ with a requirement that the tracing can be enabled or disabled at runtime using JMX so that i can change the value using jconsole/HtmlAdaptorServer. Now again i have to keep the Pointcut in AOP.xml file so that we can change the poincut when need.
