Provide the admins a log of object access (who accesses a project, report, dashboard, etc...)

We really need logging on all objects and also on exactly what a user is doing once they log in.

We need the ability to keep our systems up to date. Right now, I can't tell how often a report or dashboard is used - so I am not able to clean up items. (Even with Filters, Views, Groups -- I can't tell how often they are used, or not used.)

We would like to know who & when someone accesses items - a report, a project, a portfolio.

To push adoption, I need to know what a user is doing when they access. When a user logs in, what are they doing & when. I want more than just last log-in date. ex; I need to know if a user is only logging in once a week to log time on a timesheet, or are they using the application all week.
