I don't think nowadays something like this is too useful. You want to gather more info about users than simply counting page loads, and the various analytics services can do that. If you want to go full server-side (as opposed to e.g. Google Analytics requiring JS and the consent of users) then something like Azure Application Insights provides ample data.
