Ayup,

I have a Docker setup (E, L & K w/ compose) which has its Logstash parsing custom logs. The "Sophos" pipeline only outputs to an elastic node.

However; Logstash It thinks its super funny to _also_ print every single message to STDOUT despite there being no output for that.

It didn't originally do this, something changed in the pipeline during development. I think it might have started when I added RUBY maths in part of the pipeline, but I can't remove any of that as its in production now.

```
output {
  elasticsearch {
    hosts => "https://<elastic_host>:9200"
    cacert => "<path>/ca.crt"
    user => "logstash_writer"
    password => "<pword>"
    index => "sophos_xg-7.8.1-%{+MM.YYYY}"
    ssl_certificate_verification => true
  }
}

```

RUBY example (they're all like this):

```
ruby {
        id => "calculate total_cpu"
        code => "event.set('total_cpu', (100 - event.get('idle').to_f).round(2))"
      }

```

So far I've tried:

- Using compose's `--log-level CRITICAL`
- Explicitly disabling Logstash debug modes
- Swearing

Without using physical violence; how do I stop this occuring? It's taking up cycles to do this and making Logstash debuging hard af

Thanks!
