Hi,

If you parse a JSON with filebeat and send it in elasticsearch, all root keys from the original json document will have the prefix `json.<fieldname>`. For example

```auto
{"status":400} -> {"json" : { "status" : 400}}

```

Right?

So can we change this `json` name to something of our own liking or should we rewrite everything using logstash/ingest. (for example `{"webservername":{"status":400}}`)

Hi,

Currently there is no way to do it, you can only choose to write it under the `json` key or directly under root with [`json.keys_under_root: true`](https://www.elastic.co/guide/en/beats/filebeat/6.2/configuration-filebeat-options.html#config-json).

In the upcoming 6.3 release we add a new [`rename` processor](https://www.elastic.co/guide/en/beats/filebeat/6.3/rename-fields.html) that can be used to rename fields in any way.
