There is some way to have a trigger from snmp events (without a entire zabbix or nagios)

Hi , i want to receive snmp events (esx and vcenter) and use these snmp events triggering tasks , there is a way without installing a entire zabbix?
i was trying with snmptrapd loggin to a file , but i am stuck that i cant connect the new event in the log file to a trigger.
