In my filebeat configuration, I am trying pass json file to filebeat and want specific fields in the json to filtered and passed to elasticsearch. I am not using logstash. Below is my filebeat config:

```
- type: log
  paths:
     - /var/log/test4*.json
  json.keys_under_root: true
  json.add_error_key: true
  processors:
    - decode_json_fields:
        fields: ["header"]
        process_array: false
         max_depth: 1

```

Example of my json file:

> {"header1": "nissan"},  
> {"header": "mazda"},  
> {"header": "honda","cars":["civic", "accord", "clarity"] }

I would like only the following to sent to Elasticsearch.

> {"header": "mazda"},  
> {"header": "honda"}
