How to enable JMXMP in Tomcat?

由 旧街凉风 提交于 2019-11-29 21:42:41
问题 I've downloaded the JMXMP extensions and installed them in Tomcat's lib directory. Now, how can I make it use them, i.e. let Tomcat accept JMXMP connections? Oracle's examples show how to do it with code, for which I'd have to write my own listener, which I'd rather keep as a last resort. Tomcat's JMX listener does not seem to include JMXMP support. 回答1: Well, I wrote my own JMXMP Tomcat listener. Feel free to use: package webersg.tomcat; import java.lang.management.ManagementFactory; import

Is a good idea to enable jmx (lambda probe) on a production server?

由 被刻印的时光 ゝ 提交于 2019-11-29 20:42:55
We are experiencing some slowdowns on our web-app deployed on a Tomcat 5.5.17 running on a Sun VM 1.5.0_06-b05 and our hosting company doesn't gives enough data to find the problem. We are considering installing lambda probe on the production server but it requires to enable JMX (com.sun.management.jmxremote) in order to obtain memory and CPU statistics. Does enabling JMX incur a serious performance penalty? If we enable JMX, are we opening any security flaw? Do I need to setup secure authentication if we are only enabling local access to JMX? Is anyone using the same (tomcat + lambda probe)

Support for Kerberos Authentication/Authorization on JMX Client/Server running on Java 6

由 别等时光非礼了梦想. 提交于 2019-11-29 20:31:37
问题 I have my JMX server which registers beans reading from local file and make them available to other JMX clients on demand. Server can be accessed either using "jconsole" or by Java app running under Tomcat container. What i want is to add authentication in order to prevent "unknown" identity accessing JMX Server. To achieve this i have added Kerberos authentication @ server using following JVM options -Dcom.sun.management.jmxremote=true -Dcom.sun.management.jmxremote.port=5555 -Dcom.sun

How to find the default JMX port number?

由 白昼怎懂夜的黑 提交于 2019-11-29 19:25:50
I am running a Java application on Java 6 VM on a remote Windows XP, on which I can run jvisualvm.exe to connect to the running application automatically. Now I need to connect that application from my local computer, but I don't know the JMX port number of the remote computer. Where can I find it? Or, must I restart that application with some VM parameters to specify the port number? After reading the question How to find the JMX port in a server , I executed the command on the remote computer netstat -apn but got nothing. Now I need to connect that application from my local computer, but I

Explain JMX URL

由 余生颓废 提交于 2019-11-29 18:51:18
I am trying to understand a JMX service URL. service:jmx:rmi://192.168.30.10:1234/jndi/rmi://192.168.30.10:2344/jmxrmi It would be great, if someone can help me understand this. Thanks David Tonhofer I will reuse an answer I wrote up earlier for this question: Cannot connect to Tomcat's MBeanServer via jconsole in Java6 It's not complete, but might help: Suppose you have the JMX Server (alias 'JMX Agent' alias 'the JVM you want to connect to') running on 'TARGET MACHINE' with the RMI registry port at 'RMI REGISTRY PORT' and the JMX RMI server port at 'JMX RMI SERVER PORT'. Note: The RMI

How to configure Hibernate statistics in Spring 3.0 application?

由 大兔子大兔子 提交于 2019-11-29 14:43:34
问题 How do we configure such that we obtain Hibernate statistics through JMX in Spring MVC based web applications. Is there any better way of tracking Hibernate performance. 回答1: Set hibernate.generate_statistics to true (either in persistence.xml or in hibernate.cfg.xml or in your session factory bean configuration). Then register this bean: <bean id="hibernateStatisticsMBean" class="org.hibernate.jmx.StatisticsService"> <property name="statisticsEnabled" value="true" /> <property name=

Is there any JMX - REST bridge available?

问题 Hi I would like to monitor a Java application using the browser but at the same time utilising the existing JMX infrastructure. I know that JMX provides a HTTP interface but I think it provides a standard web gui and its not possible to mashup its functionality with an existing system. Are you aware of any REST interface for JMX? My research on google currently shows that there is one project which does something similar. Is this the only option? 回答1: Jolokia is a new (at this time) JMX Agent
