Hi Wes, I submitted 1723611 for the new RMON alarmTable code. I also have some update bug report on netsnmp_iquery_pdu_session().
I changed to use netsnmp_iquery_pdu_session() instead of
netsnmp_iquery_user_session() by switching #if 0 to 1 at the end of
alarmTable.c.
(See attached file: alarmTable.c)
It seems netsnmp_iquery_pdu_session() only works with pdu of
SNMP_VERSION_3, the following sequence works fine to generate alarmRising
notification.
snmpset -v3 -ufoo 10.1 eventStatus.1 i 2
snmpset -v3 -ufoo 10.1 eventStatus.1 i 1
snmpset -v3 -ufoo 10.1 eventType.1 i 4
snmpset -v3 -ufoo 10.1 alarmStatus.1 i 3
snmpset -v3 -ufoo 10.1 alarmVariable.1 o ifInOctets.3
snmpset -v3 -ufoo 10.1 alarmStatus.1 i 1
But it doesn't work with pdu of SNMP_VERSION_2c, the following sequence
caused infinite loop.
snmpset -v2c -cprivate 10.1 eventStatus.1 i 2
snmpset -v2c -cprivate 10.1 eventStatus.1 i 1
snmpset -v2c -cprivate 10.1 eventType.1 i 4
snmpset -v2c -cprivate 10.1 alarmStatus.1 i 3
snmpset -v2c -cprivate 10.1 alarmVariable.1 o ifInOctets.3
snmpset -v2c -cprivate 10.1 alarmStatus.1 i 1
Since the debug log(attached at the end of the email) looks so similar to
internal query for delegated objects, only this time it is not delegated
object but the query session is derived from SNMP_VERSION_2c pdu, I suspect
there may be some problem in internal query session creation.

Thanks very much for contributing to the rmon code! It certainly
needed work.
If possible, please always submit your patches to our patch database
so we can properly track them and ensure we can't forget about it!
