Hello.

I want to get only specific fields in filebeat data. I know there is a prune filter in logstash config file but which one is same thing in filebeat config file processor?

I used include\_fields processor, but it doesn't working. The result was that all the fields were shown up.

Thank you.

The processor is the `include_fields` to only include some fields or `drop_fields` to only drop some fields.

It is not clear why it doesn't work as you didn´t share your configuration or any other evidence of this.

Please share your `filebeat.yml` configuration and a sample of your message.
