Monitoring Activity

In the world today of many working from home it seems like it would be a good enhancement to be able to see more about what they are doing.  In addition to the duration of the session I was hoping to find something that might indicate more statistics such as keystrokes, mouse clicks, volume of data transmitted, etc.  Basically see that when somebody is working remotely they are actually “working” and not sleeping or taking a nap!  Technically somebody could login for 8 hours and do nothing without being able to tell from the activity report.
