Hi,

I'm using 4 pipelines with a single **Logstash** instance. The logs are all mixed up in a single **Logstash** output log file (_/var/log/logstash/logstash-plain.log_). Is that possible to say like _"pipeline.id=A directs to the log logstash-A.log"_ (_/var/log/logstash/logstash-A.log_) ?

That would be a good thing to have!

Thanks!
