Try using "extend dhcpd_partner_down /root/dhcpd_partner_down.sh" instead,
and then run
snmpwalk -v 2c -c public localhost nsExtendObjects
That will give you essentially the same output, but with a proper
MIB file to display it in a sensible fashion. (In particular, to interpret
the index to the table properly). You should then be able to see
where this long OID is coming from.

Yes.

Why do you want three copies of every trap?
Typically, you should use "trapsink" OR "trap2sink" OR "informsink".
Not all three.

Try using
monitor -r 60 -o .1.3.6.1.4.1.3658.5000 "Partner Down2"
SNMPv2-SMI::enterprises.3658.50.3.1.4 != 0
or, if you're using the version of extend without an explicit root OID, try
monitor -r 60 -o .1.3.6.1.4.1.3658.5000 "Partner Down2"
nsExtendResult != 0

What do you see if you run "snmpwalk ... SNMPv2-SMI::enterprises.3658.50.3.1.4 "
(or "snmpwalk .... nsExtendResult", as appropriate)?
What exit value does your dhcpd_partner_down.sh script return?
