SNMP trap parsing

[Joep]

Hi!

I have some issues parsing SNMP traps.

My SNMP trap looks like:

2021-08-17 11:29:28
11:29:26 2021/08/17 PDU INFO:
messageid 0
errorstatus 0
receivedfrom UDP: [172.25.6.196]:57319->[172.25.1.6]:162
transactionid 160
requestid 1
version 1
notificationtype TRAP
community public
errorindex 0
VARBINDS:
iso.3.6.1.2.1.1.3.0 type=67 value=Timeticks: (63245865) 7 days, 7:40:58.65
iso.3.6.1.6.3.1.1.4.1.0 type=6 value=OID: iso.3.6.1.4.1.35833.6.254.0.1
iso.3.6.1.4.1.35833.6.2.8.1.0 type=4 value=STRING: "MER-Stiltedetector-01"
iso.3.6.1.4.1.35833.6.2.8.1.0 type=4 value="INTEGER: "2"
iso.3.6.1.4.1.35833.6.2.7.3.5.0 type=4 value="INTEGER: "128"

I created an item which gets the message as a TEXT:

snmptrap["iso.3.6.1.4.1.35833.6.254.0.1"]

After that I have 1 trigger which fires when message contains trapper id:

DEVA alert: {{ITEM.VALUE}.regsub("iso.3.6.1.4.1.35833.6.2.8.1.0\stype=4\svalue=STRING:\s(.*)", Problem ID: \1)}

with expression

find(/Template Deva DB8008/snmptrap["iso.3.6.1.4.1.35833.6.254.0.1"])<>0

I would like to know if it's possible to:
- map all three SNMP lines to values
- use these values in my triggernames
- use value mapping for the integer values (=1 => Main / =2 => Backup) so my trigger has readable text instead of integers

Hope someone can help me out here!
