Hi,

I want to ship data from Logstash A (client) to Logstash B (server).

Logtash A will need to decode netflow traffic, add and remove some fields and then send it to Logstash B for further processing and finally send data to Elastic.

I've got a lumberjack output and input working, I'm receiving data but it doesn't appear lumberjack is outputting any data.

Received data:

```auto
{
  "_index": "test2017.10.13",
  "_type": "logs",
  "_id": "AV8T7SDgV08ceArt086i",
  "_version": 1,
  "_score": null,
  "_source": {
    "@timestamp": "2017-10-13T04:10:28.433Z",
    "input_name": "input_location_a",
    "@version": "1",
    "message": "2017-10-13T04:08:25.000Z 10.0.0.246 %{message}"
  },
  "fields": {
    "@timestamp": [
      1507867828433
    ]
  },
  "sort": [
    1507867828433
  ]
}
```

This doesn't contain any of the netflow data.

Client config

```auto
input {
   udp {
     port => 9995
	codec => netflow {
	versions => [9]
	}
       }
}

filter {
 mutate {
    add_field => { "output_location_name" => "output_location_a" }
}
}

output {
  lumberjack {
          id => "fortinetflowtest"
          hosts => "ipofserver"
          port => 9998
	  ssl_certificate => "/etc/pki/tls/certs/logstash-forwarder.crt"
      }
}
```

Server config

```auto
input {
  lumberjack {
    id => "fortinetflowtest"
    port => 9998
    ssl_certificate => "/etc/pki/tls/certs/logstash-forwarder.crt"
    ssl_key => "/etc/pki/tls/private/logstash-forwarder.key"
  }
}

filter {
 mutate {
    add_field => { "input_name" => "input_location_a" }
}
}

output {
elasticsearch {
hosts => localhost
index => "test%{+YYYY.MM.dd}"
  }
}
```
