input {
        beats {
                port => 5044
        }

        snmptrap {
                type => "snmptrap"
                community => "public"
                port => 8162
        }
}

filter {
  if "_grokparsefailure" in [tags] {
        drop {}
  }
}

                index => "%{[index]}-%{+YYYY.MM.dd}"
