Another method is to tap into existing knowledge, through the Zabbix database. As the database already holds information on host/IP address relationships, we can simply look up the corresponding hostname. Let's modify snmptraps.sh so that all traps coming from hosts defined in Zabbix end up in an snmptraps item for that specific host, but other traps are collected in the generic snmptraps host instead.
Start by modifying /home/zabbix/bin/snmptraps.sh and adding two lines:
oid=`echo $oid|cut -f11 -d'.'` community=`echo $community|cut -f2 -d'"'` zabbixhost=$(HOME=/root mysql -N -e "select host from zabbix.hosts left join zabbix.interface on zabbix.hosts.hostid=zabbix.interface.hostid where ip='$hostname' order by 'hostid' limit ...
