filebeat-5.5.1 got decoding JSON with a simple json line string:

```json
echo {"id":"l7KVoUhkRWWESd9QE_DX5Q", "timestamp":1502334971,"logtype":"event", "file":"tset.cpp", "function":"ProcMessageNew", "line":271} >> test.log 

```

filebeat is monitoring the test file:

```auto
- input_type: log
  paths:
    - /root/test.log

```

also I try the newest version filebeat, got the same issue. @steffens

You have to [explicitly enable json parsing](https://www.elastic.co/guide/en/beats/filebeat/current/configuration-filebeat-options.html#config-json). The way you use the echo command, without additional escaping I'm not sure a valid json line will be written to your log.
