SnmptrapD executes the perl script which translates the trap to the format that is right for the Zabbix server (basically adding a header). In this case the information is sent from a SNMP-enabled device and is collected or trapped by Zabbix. For better performance on production systems, use the embedded Perl solution (either script with do perl option or SNMPTT). Zabbix checks if the currently opened file has been rotated by comparing the inode number to the defined trap file's inode number. This example uses snmptrapd and a Bash receiver script to pass traps to Zabbix server.
