[jboss-user] Exporting JMX attributes over SNMP: JMX, snmp-adaptor.sar and Spring

[Marc Schoechlin]

Hi,

i wrote 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
