Hello,
   I've been trying to figure this out without much success. Maybe I
just don't know exactly what to look for but I can't seem to find the
answer. I would be grateful for any help someone could give me.
   What I've done is setup a couple monitors in my snmpd.conf file.
When it triggers I know the event occurred but the information
contained in the trap isn't very useful. Here is the information that
is received from the trap:

Notification that the trigger indicated by the object instances has
fired, for triggers with mteTriggerType 'boolean' or 'existence'.
mteHotTrigger: nra2Tomcat;
mteHotTargetName: ;
mteHotContextName: ;
mteHotOID: .1.3.6.1.4.1.8072.1.3.2.3.1.4.15.110.114.97.50.84.111.109.99.97.116.67.104.101.99.107;
mteHotValue: 0;

The monitor config in my snmpd.conf file looks like so:
monitor -r 300 -I -u public nra2Tomcat nsExtendResult."nra2TomcatCheck" != 0

That script also produces output that I would like to include in the
trap. If I do an snmpwalk I get:
NET-SNMP-EXTEND-MIB::nsExtendCommand."nra2TomcatCheck" = STRING:
/home/fedil/scripts/websiteCheck/websiteCheck.php
NET-SNMP-EXTEND-MIB::nsExtendArgs."nra2TomcatCheck" = STRING: x.x.x.x
ds/svc/ipg_shows
NET-SNMP-EXTEND-MIB::nsExtendInput."nra2TomcatCheck" = STRING:
NET-SNMP-EXTEND-MIB::nsExtendCacheTime."nra2TomcatCheck" = INTEGER: 5
NET-SNMP-EXTEND-MIB::nsExtendExecType."nra2TomcatCheck" = INTEGER: exec(1)
NET-SNMP-EXTEND-MIB::nsExtendRunType."nra2TomcatCheck" = INTEGER: run-on-read(1)
NET-SNMP-EXTEND-MIB::nsExtendStorage."nra2TomcatCheck" = INTEGER: permanent(4)
NET-SNMP-EXTEND-MIB::nsExtendStatus."nra2TomcatCheck" = INTEGER: active(1)
NET-SNMP-EXTEND-MIB::nsExtendOutput1Line."nra2TomcatCheck" = STRING:
Webpage has content!
NET-SNMP-EXTEND-MIB::nsExtendOutputFull."nra2TomcatCheck" = STRING:
Webpage has content!
NET-SNMP-EXTEND-MIB::nsExtendOutNumLines."nra2TomcatCheck" = INTEGER: 1
NET-SNMP-EXTEND-MIB::nsExtendResult."nra2TomcatCheck" = INTEGER: 0
NET-SNMP-EXTEND-MIB::nsExtendOutLine."nra2TomcatCheck".1 = STRING:
Webpage has content!

So how can I include the nsExtendOutLine to the event that gets
triggered and sent as the snmp trap? Or other custom varbinds? I'm
fairly new to SNMP so please be as descriptive as possible.

Thanks,
Fedil
