Hello,

I am using the logstash docker image and a pipeline from tcp to elastic search. Whenever a message is processed by logstash it is also output to stdout, even though I have logging turned to warn or above. There are no error messages, only the processed message which is sent to elasticsearch.

Is there any simple way to disable this logging to stdout?

Here are my pipeline and settings yml

```
input {
  tcp {
    port => 8001
    codec => json_lines
  }
}

filter {
  mutate {
    add_field => {
      "server_time" => "FAILED"
    }
  }

  date {
    timezone => "UTC"
    match => ["[doc][time]", "UNIX_MS" ]
    target => "server_time"
  }
}

output {
  elasticsearch {
    hosts => ["elasticsearch"]
    index => "tcp_log-%{+yyyy.MM.dd}"
  }
}

pipeline:
  batch:
    size: 500
    delay: 25
  workers: 16
config:
  debug: false
log:
  level: error
```
