First, thank you for the detail, and for formatting things. It really does help 
A few things;
- I can't see that you have enabled a module for filebeat in your detailed steps, so it won't be processing any files. This doesn't match with your
filebeat modules listabove so I just wanted to double check that - in Step 7 you set an input to true, which input was this?
- What do the filebeat logs show?
