Measuring User Activity on Orion

Hi

Been a while since I've asked my last question. So here goes.

I have a lot of users on my Orion deployment. Is there any way e.g. a report or a script, which I can use to check the following:

1. How many users are logged onto SolarWinds at any given point of time.
   
   
2. Which users have been most active/inactive for a certain period of time
   
   

Looking forward to any suggestion

Regards
