Sending Logs to ELK/Logstash

Hello - Has anyone had success ingesting logs into logstash and has a config they could share? I’ve been trying to use a network/port input in my config with a json filter, and while the network connectivity is fine, I don’t see any logs making their way to Kibana or even Elasticsearch from LS. Not sure if filebeat is maybe the preferred method since there’s an “experimental” module for it. Any direction would be appreciated!
