I suggest you use `drop_event` processor to do so: [https://www.elastic.co/guide/en/beats/filebeat/master/drop-event.html](https://www.elastic.co/guide/en/beats/filebeat/master/drop-event.html)

Please format your configuration using `</>`. It possible that you have a whitespace error in the processors configuration.
