Hi and welcome ixvega
I would not recommend relying on any internal Drupal analytics. There is the Statistics module which is explained here:

However, tracking analytics is *very* database intensive and will either be inaccurate or it will swell your database to an enormous size.
If you can't use Google Analytics, perhaps consider an alternative such as
