Two filebeat instances

Like yodog, I need to route Project A prospectors (4) to Logstash Port 1 and Project B prospectors (2) to Logstash Port 2. It is odd to me that this common use case is not supported without running another Filebeats instance.

That said, where can I find a how-to guide to run two different Filebeats instances beyond:

Yes, you can run two filebeat instances in parallel. Make sure they use a different data directory so they have 2 different registrar files.
