Zabbix may also receive traps that are parsed by SNMPTT: http://www.snmptt.org/. This method uses the same temporary file and internal process approach as the embedded Perl trap receiver solution. SNMPTT can be useful for making received data human-readable.

Remember that it changes passed data so, depending on how things are set up, adding SNMPTT might require changes to item mapping, triggers, or other configuration.
