How to create a trigger for SNMP Trap?

[Jarne St]

Hello,
This is maybe a very trivial question, but how can I make a trigger if I receive a SNMP Trap.
This is the trap that I receive:

16:13:13 2019/10/09 ZBXTRAP 172.27.0.172
PDU INFO:
  messageid                      0
  requestid                      160506603
  community                      private
  transactionid                  2
  errorindex                     0
  receivedfrom                   UDP: [172.27.0.172]:50188->[172.27.0.162]:162
  errorstatus                    0
  version                        1
  notificationtype               TRAP
VARBINDS:
  DISMAN-EVENT-MIB::sysUpTimeInstance type=67 value=Timeticks: (0) 0:00:00.00
  SNMPv2-MIB::snmpTrapOID.0      type=6  value=OID: IF-MIB::linkDown

This is just plain text, so what will be the trigger expression?
