I was originally taking a look at that a few months ago, but since I have a few other small sites I also wanted to switch over (some of which aren't even on hosts I control), I decided to give Fathom a go.

Honestly, it would be best if there were an easy way to aggregate the logs into something like Fathom or GoAccess from any server with a little daemon running... but well, that's how I do it for larger sites with an EFK-based cluster. It just takes a lot more resources and maintenance!
