Tracking User movements

Does anyone track user movements and if so what do you set up? This is for an internal administration system.

From simple recording of when a user logs in
through to

• which pages they visit?
• which forms and buttons they press?
• which form fields did they fill in and with what information?

This could be a massive undertaking in itself. I don’t want to make it too complicated yet I need the information to be usable.

My reasoning is to have a basic audit trail of who did what and have that viewable as on-screen reports. There may be 2 reports…

1. What did User A do today? And which projects did they work on?
2. Who worked on Project B3 and in what areas of the project?

I am looking for ideas/suggestions.
