Hi, I'm including my dockers json logs to the ELK stack, but I can't send them to ES and I don't know why not  
My filebeat shipper look like this:

> ```
> - type: log
> paths:
> json.message_key: log
> json.keys_under_root: true
> fields.doc_type: json_docker
> 
> ```

My Logstash config file just do this:

> ```
> output {
> if [fields][doc_type] == "json_docker" {
> elasticsearch {
> hosts => ["10.0.11.30:9200"]
> sniffing => true
> manage_template => false
> index => "%{host}_json-%{+YYYY.MM.dd}"
> }
> }
> }
> 
> ```

With `keys_under_root` enabled the `doc_type` field won't end up under `fields`. Dump the event with a `stdout { codec => rubydebug }` to inspect exactly what you have.
