The SnmpAgentService exposes a standard MIB2 System Group. However, the OIDs that are produced violate RFC-1213, which dictates that the sysUpTime value should have a type of TimeTicks. Instead, SnmpAgentService generates a type of int32.
Take the following output from snmpwalk:
SNMPv2-MIB::sysDescr = STRING: Central Computer
SNMPv2-MIB::sysObjectID = OID: SNMPv2-SMI::enterprises.18016.1.1.2
SNMPv2-MIB::sysUpTime = Wrong Type (should be Timeticks): Gauge32: 769331
SNMPv2-MIB::sysContact = STRING: Agent Smith
SNMPv2-MIB::sysName = STRING: email@example.com
SNMPv2-MIB::sysLocation = STRING: In The Matrix
SNMPv2-MIB::sysServices = INTEGER: 64
End of MIB
For systems which monitor SNMP agents (e.g. OpenNMS), this causes them to reject the agent because of the bad type.
The bug lies in org.jboss.jmx.adaptor.snmp.agent.RequestHandlerImpl, which determines the type of the OID value by examining the type of the JMX attribute being monitored. It has no way to generate a TimeTicks value, it can only handle Long, String, Integer and SnmpOID types.
The JBoss wiki states that RFC-1213 is supported, but this is incorrect when the type for sysUpTime is wrong (http://wiki.jboss.org/wiki/Wiki.jsp?page=JBossSNMPAdapterGetValues). Also the attributes.xml file in xnmp-adaptor.sar quotes RFC-1213.
