gam report customer
is a good start. Here it is on my test domain (so numbers are low) but gives a decent overview of student/teacher interactions. 1day students are students who have interacted within 24 hours before report, 7 day, etc So 1day student should be counted as 7day also (which should always be same or larger number). Showing only fields that may be of interest to your reporting. Note that this data will be 48-72 hours behind. As I run it now on Friday 4/3 the newest data available is from Tuesday 3/31.
