Here's a little program to integrate snmp traps into your mon setup.
It's meant to be used as an 'EXEC'ed program from snmptt
(http://snmptt.sf.net), which does most of the heavy lifting.
I had written something like this in the past that got lost, I'm
sending out this version to the list for storage in contrib/ or,
minimally, in google's archive :-)
As the comment block says:
# to be used in conjunction with snmptt : it hands us
# the results of an snmp trap and we forward it on in
# a format mon will understand.
# usage:
# snmptrap2mon [(--watch|-w) watchname] [(--service|-s) servicename]
# [(--host|-h) hostname] [(--name|-n) trapname] [(--time|-t) timestamp]
# "Quoted longform text of alert to send"
# - 'watchname' and 'servicename' should map to your mon config;
# leave them off and they will be set to 'default'
# - 'host' is the host sending the trap, as best snmptt can tell
# - 'trapname' is the unique string configured for this trap in snmptt.conf
# - 'timestamp' will be the time alert was received/queued ($x or $X)
#
# Example, from /etc/snmp/snmptt.conf:
# EVENT communicationLost .1.3.6.1.4.1.318.0.1 "Status Events" CRITICAL
# FORMAT APC UPS: Communication lost between the agent and the UPS.
# EXEC snmptrap2mon -w symmetra-ups -s trap -h $A -n $N \
# -t "$x" "APC UPS: Communication lost between the agent and the UPS."
#
# See README.traps in the mon distribution to setup your mon.cf.
