Dear Ivy Team Doing some performance analysis since our app is using a lot of CPU. I've activated JAVA_OPTS="$JAVA_OPTS -Dcom.sun.management.jmxremote.port=9003 -Dcom.sun.management.jmxremote.login.config=jmx -Djava.security.auth.login.config=configuration/jaas.config -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.autodiscovery=true" JAVA_OPTS="$JAVA_OPTS -Djava.rmi.server.hostname=<ip>" When I connect with Java Mission Controller to Ivy 7 I get the following results :
java.lang.RuntimeException: Access denied! Invalid access level for requested MBeanServer operation. at com.jrockit.mc.flightrecorder.controlpanel.ui.FlightRecorderProvider.refresh(FlightRecorderProvider.java:110) at com.jrockit.mc.browser.views.JVMBrowserView$1.run(JVMBrowserView.java:100) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) at java.util.concurrent.FutureTask.runAndReset(FutureTask.java:308) at Caused by: java.lang.SecurityException: Access property for this identity should be similar to: readwrite create com.sun.management.MissionControl at .... According to https://community.oracle.com/thread/2588377 : You need to ensure that the user you want to access the flight recorder has permission to create the relevant MBeans. You have probably defined the roles in the jmxremote.access file. Try adding: <your-role-name-goes-here> readwrite \ create com.sun.management.,com.oracle.jrockit. \ unregister => where can I change this for Ivy ? Thanks & Regards John |
Hi John You are right if you want to access JFR from Java Mission Control on a remote machine then you have to enable this in the jmxremote.access file as follows: Change from:
to:
as described in the articel https://community.oracle.com/thread/2588377 The file can be found here: Windows: Axon.ivy Engine < 7.4: {engine installation dir}/jre/lib/management/jmxremote.access Axon.ivy Engine >= 7.4: {engine installation dir}/jre/conf/management/jmxremote.access Linux: Axon.ivy Engine < 7.4: {java installation dir}/jre/lib/management/jmxremote.access Axon.ivy Engine >= 7.4: {java installation dir}/conf/management/jmxremote.access |
Follow this guide to login with your ivy admin user.: https://developer.axonivy.com/doc/7.0.14/EngineGuideHtml/monitoring.html#monitoring-jmx visualvm 1.4.4 (latest) contains stacktraces re hot methods. Maybe need to define -Dcom.sun.management.jmxremote.port=9003 -Dcom.sun.management.jmxremote.rmi.port=9003 with visualvm 1.4.4 it's ok |
