Email Alert for SNMP Trap

I have configured snmptrapd with a MIB file and now when I receive traps, the associated logs include a readable description of the received trap in the message field as expected. Now I want to send an email alert with that message. I tried editing the Alert Template according to: however there is no “Placeholder” for the message parameter. How can I send an email alert that includes the message parameter to let the recipient know what went wrong?

bash-4.2$ ./validate.php

Working on the same problem here…

Trap Message : {{ $value[‘message’] }}

^^^ this solved it for me. (in the alert template)

Nice one, thank you! I see now that any of the iterated values must be enclosed in double braces, not just the special field $value['string'] as described in the doc.
