GoAccess is great and all, but static log analyzation =/= Google Analytics. You can only get so much data via log analysis, and if you have a SPA, or even just alot of client side stuff, static log analyzation just cannot provide you with the same type of data you get from client side.
If you really want to replace Google Analytics and have the same level of features and tracking you need a client side system - Matomo is the closest I've seen to that.
All that being said, I've used GoAccess, I like it, but I haven't quite mastered the log format to enable my more robust AWStats logs with GoAccess. I have a bunch of subdomains all as VHosts, and I loved the feature in GoAccess that rolls it all up into a VHost table/chart. However I haven't figured out the log parser settings to get both AWstats and GoAccess to like it with the %v_host field in the logs. Any thoughts/help there?
