User Activity Tracking in NAV2009R2

Hi,

I'd like to track the following User Activities in NAV RTC.
What would be the best functionality that I can use to achieve the logging?

1) Track (specific Date & Time of) Login & Logout from RTC Client
2) Track (specific Date & Time of) the change in Company Database user logged into. (ex. from CRONUS USA to CRONUS Canada)
3) Track which user opened/accessed which Page & Reports.

For 1), I was thinking about Time Register, but found out that it will only track Date and total minutes accessed in NAV, so it wouldn't do the job, as individual Login and Logout entries need to be logged.
For 2) and 3), I have no clue whether there are any default functionality in NAV that would allow me to log the activity, instead of modifying each Page/Reports. Are there any good idea?

I can think of using SQL Profiler, but since it would not run as a service, and it needs to be open all the time, I was thinking if there were any functions that I could use in NAV, that would not overload the performance of the server.

I would greatly appreciate your advice on this.

Thank you.
