i have defined a lot of yaml for snmp trap that i want , and put these yaml in my mib directory(specificmibs), and defined the mib directory in my conf as follows, yamlmibdir =\> "/opt/logstash/vendor/bundle/jruby/1.9/gems/snmp-1.2.0/data/ruby/snmp/specificmibs" but how to remove the event when the mib can't found in yamlmibdir ? How can I make logstash drop it? ---

This question is almost word for word the same as [[drop] the same message](https://discuss.elastic.co/t/how-to-remove-an-trap-event-from-logstash/46955). Are you posting using multiple accounts? What does a message that you want to drop look like and what does a message you want to keep look like? ---
