  • 1.  CA Wily , java agent for Jboss EAP 6.3

    Posted Nov 24, 2016 05:04 AM

    Hi ,

     

    We have installed CA Wily agent for CA using the Jboss configuration steps as mentioned in the installation guide as available on CA Support portal.

    We have made the desired changes to the introscope.profile and standalone.conf files as required and we were able to see the metrics for the GC and JMX .But we can't see the backend and frontend nodes even if the instance is being called.

    We have checked the agent's log file and we got this error :

     

    11/23/16 04:36:35 PM WET [ERROR] [IntroscopeAgent.Agent] IntervalHeartbeat.execute threw executing: IntelligentInstrumentationService
    java.lang.NullPointerException
    at com.wily.introscope.probebuilder.intelligent.instrumentation.IntelligentInstrumentationConfig.initVisibilityGapProcessor(IntelligentInstrumentationConfig.java:488)

    at com.wily.util.heartbeat.IntervalHeartbeat$HeartbeatRunnable.run(IntervalHeartbeat.java:668)
    at java.lang.Thread.run(Thread.java:745)

     

    We have searched for a solution for this issue and we found that it is a problem that often occurs while using Jboss EAP 6.3 and the solution is to remove the comment from the  line  : TurnOn : MethodClassLevelInstrument ( in appmap.pbd).The problem is that there is no comment on that line so the flag is already being used.

     

    We are using Jdk 1.7

    Hello,

    There may be other root causes for that exception.

    1. Can you please confirm agent version?
    2. If Smart/deep instrumentation is enabled, which it is by default (introscope.agent.deep.instrumentation.enabled=true) please try to disable it & restart JBoss to see if that helps.
    3. If problem still persists please enable DEBUG in agent profile & restart JBoss
      • log4j.logger.IntroscopeAgent=INFO, logfile
      • log4j.appender.logfile.MaxFileSize=100MB

    Then upload the introscopeagent.log & autoprobe.log files.

     

    Thanks
