Jboss->snmp-adaptor->snmptrapd->snmptt configuration issue

[karanuk]

Hello,
I needed to investigate jmx-notifications -> snmp traps -> nagios(1.3) ->alert process.Got the the snmp-adaptor.sar configured as
jboss-service.xml
-----------------------------------------------------------
<?xml version="1.0" encoding="UTF-8"?>


org.jboss.jmx.adaptor.snmp.agent.RequestHandlerSupport
org.jboss.jmx.adaptor.snmp.agent.TrapFactorySupport
/notifications.xml
/managers.xml
0
1161
false

<subscription-list>
<mbean name="jboss.jmx:name=HelloWorld,service=test,type=testBroadcaster"/>
</subscription-list>


-----------------------------------------------------------
manager.xml
__________________________________________

172.19.22.250
162
<local-address></local-address>
<local-port></local-port>
1

__________________________________________
and notifications.xml as
------------------------------------------------------

<notification-type>com.acme.jmx-smnp.test</notification-type>
0
0
.1.3.6.1.4.1.2162.500.1.1
<var-bind-list wrapper-class="org.jboss.jmx.adaptor.snmp.agent.NotificationWrapperSupport">
<var-bind>
n:message
.1.3.6.1.4.1.2162.500.1.1.1
</var-bind>
</var-bind-list>

------------------------------------------------------
where com.acme.jmx-smnp.test is the notification-type emitted by mbean jboss.jmx:name=HelloWorld,service=test,type=testBroadcaster.
The case happening being that with a configured snmptrapd+snmptt combination the above trap is gettig accepted as "coldStart" trap and the notification type "com.acme.jmx-smnp.test" accepted as "coldStart" trap variable.
If someone faced such issue previously or if i'm making here some configurations mistake,do let me know.

thanx in advance,
karanuk

When you post your configuration/descriptors in the forums, wrap them using:

[ code ]

[ /code ]

(without the spaces)

The conf xml tags seems to have got dropped.The descriptors r as bellow.

Hi,
Was just debugging and found that the generic and specific tags in the notifications.xml are overriding the enterprise OID and so the coldStart trap's being sent.

notification-map-list>
<mapping>
 <notification-type>com.acme.jmx-smnp.test</notification-type>
 <generic>0</generic>
 <specific>0</specific>
 <enterprise> .1.3.6.1.4.1.2162.500.1.1</enterprise>
 <!--etc-->
 </mapping>
</notification-map-list>

The only document describing notifications.xml seems to be http://wiki.jboss.org/wiki/Wiki.jsp?page=JBossSNMPAdapterNotifications and as such does not detail the role of generic and specific tags.If someone knows the set of values that can be passed to these tags and their significance,plz do let us know.

looking forward for ur reply,
karanUk.

[dimitris]

Generic needs to be set to "6", meaning "enterpriseSpecific". "0" is essentially "coldStart".

Thanks Dimitris :)
That resolved the case.

It'd be nice if you can post, for the benefit of all, a sort description of how you are using the snmp adaptor with nagios. Thanks.

[karanuk]

With snmp-adaptor.sar set up to send traps,Nagios could be configured as per details in links below.
