The problem with snippets is that they are applied “globally” to your entire filebeat config file, instead of at a specified section of the config. In my case, the symlinks option needs to be applied to the “apache” or “jvm” or “whatever” prospector that I’m creating.
Also, it appears I can only have one output “host” setting per filebeat.yml - If I configure one beat collector to send to server1:5044, and another to send to server2:5044, my generated filebeat config only shows server2:5044.
Anyway, I don’t need a response or solution to this - in my case it’s not critical to my design and I was able to work around these. I was just saying that while its a very “slick” and even nice feature, it can be laborious and error prone to try to write a nice pretty GUI front end for something that was meant to be configured via txt file, and I could imagine that time and effort being spent elsewhere improving the core graylog product.
