I'm looking into getting our wowza logs in kibana. One of my predecessors has set up our ELK stack. I started filebeat, because it wasn't running on the server. I do see exim4 log entry's in kibana, but nothing related to wowza.
This is my filebeat.yml
I only added the last two entries, related to wowza.
