Session Manager

It gives you the following information:

* The number of visitors in the last day (configurable) (v1.0)
* The number of pages each visitor looked at (v1.0)
* Which pages have been looked at (v1.0)
* The times each page was visited (v1.0)
* The visitor count displayed per page (v1.1)
* Recent site activity (2.0)
* WordPress 2.7 support and restructure (v2.0)
* Support for user excludes by session_id, user_id or ip address (v2.0)
* Support for page excludes (v2.0)
* Delete data functionality (v2.0)

I find that a lot of stats plugins give a little too much information and in doing so making both the stats harder to read and analyse. Session Manager differs because what it provides is a very light weight logging implementation with a simple yet effective front end allowing you to view the data in a number of ways.
