grabbing values from SNMP Trap log file.

[redpeppers]

getting snmptrap data into proxy server just fine. I can see the data using snmptrap.fallback without any issues on zabbix gui. I am unable to grab individual values from the snmptrap data. Can anyone help me with the regex as i do not understand what i am missing....example of data and item template is below....

Data received into snmptrap log file...

I am trying to get just the value....i have messed with multiple regex but nothing is working to grab just the specific value....

snmptrap["SNMPv2-SMI::enterprises.13858.11.1.0 type=4 value=STRING: "{#SNMPVALUE}""]
