Server analytics?

Question

Google Analytics

There is a web service and a desktop client for it. They communicate using the http protocol.
You need an analytics system like Google Analytics.
The problem is that GA is inserted into the page by a script and works in the browser. I need to somehow call statistics on the server side when processing a request.
Ideas for self-implementation are also welcome.
