Accesslog functionality?
As reported in Accesslog removed from the Statistics module, the module with that functionality is the Better Statistics module, which (at the moment I am writing this answer) doesn't have a Drupal 8 version.


  The accesslog and all associated reports have been removed from the core Statistics module. This functionality exists in contrib at http://drupal.org/project/better_statistics.


There is a issue open for porting the module to Drupal 8, Port Better Statistics to Drupal 8, which was created after the change record. 

The History module in Drupal core doesn't keep a log for the access to all the pages, but it keeps a log for the access to nodes. If you are interesting just to the users who accessed a node, that could help you.
