My output contains beat ，host ，@timestamp @metadat filed as default.I want remove beat ,host fields from input.I define processor ,but it not work for beat and host filelds.I do not want to use pipeline ,because I have my own field named host,and this filed will be overwite by filebeat.
Es document say only @timestamp and type will not be remove by processor.But it is seems not work for beat ,host fields
Well.I use top levle processors ,works fine.My configruation may have some problem.
