Using Filebeats in the ELK Stack

The elk stack from the demo works well, but it only grabs docker logs. I would like to also forward the logs from an application, in this case a tomcat server, into my logstash/ELK stack. Filebeats/logstash forwarder was a way to do that before but I am new to it. Does anyone know how to configure it with the ELK stack demo or have another way of getting those logs to the ELK stack?

Thanks

check it out the filebeats autodiscover and enable the hints feature.
