    Exporting JMX attributes over SNMP: JMX, snmp-adaptor.sar and Spring

    Marc Schoechlin Newbie

      Hi,


      i implemented some jmx-attributes using Spring 3.0.
      (see spring descriptor below) 


      I start JBOSS with the following arguments:

       

       

      JAVA_OPTS="$JAVA_OPTS -Dcom.sun.management.jmxremote.port=21099 "
      JAVA_OPTS="$JAVA_OPTS -Dcom.sun.management.jmxremote.password.file=${JBOSS_CONFIGDIR}/${JBOSS_INSTANCE}/jmx.password"
      JAVA_OPTS="$JAVA_OPTS -Dcom.sun.management.jmxremote.access.file=${JBOSS_CONFIGDIR}/${JBOSS_INSTANCE}/jmx.access"
      JAVA_OPTS="$JAVA_OPTS -Dcom.sun.management.jmxremote.ssl=false"
      JAVA_OPTS="$JAVA_OPTS -Dcom.sun.management.jmxremote"
      

       

      In JConsole and VisualVM the jmx-mbeans of my war are visible - but for some reason
      these mbeans cannot be mapped in snmp-adaptor.sar.
      (see attributes.xml snippet below)

       

      I can see the following output in the jboss server.log when fetching the value by invoking snmpwalk
      (snmpwalk -v 2c  -On -c public localhost:1161 .1.3.6.1.4.1.4952.100.200.1.1):

      15:38:07,176 WARN  [SnmpAgentService] getValueFor (foobar:name=NachrichtenVerarbeitung, DatensatzLaufzeit: javax.management.InstanceNotFoundException: foobar:name=EinarbeitungsnachrichtVerarbeitung is not registered.

       

      Other mbeans (i.e. datasource jmx attributes) which are only visible in jmx-console (and not in jconsole)
      can be successfully mapped by snmp-adaptor.sar.


      It seems that this problem is caused by some type of scopeing - what can i do to make the
      mbeans of a war-application visible to snmp-adaptor.sar?

       

      Best regards
