One other thing I believe most Admins are asked to do (and don't believe I saw anything about) is monitoring & reporting on User Utilization. That is, the whats/whens/hows of SAS users logging into the environment and accessing something.

I am seemingly always asked the following:
What Users are currently logged into SAS?
How many users logged into SAS yesterday, last week, last month, etc?
What was the average amt of time a user stayed logged into SAS yesterday and last week?
What was the most commonly accessed Library and/or Dataset (by users) last week?

I find getting answers to these above questions can sometimes be quite challenging and not easily found...
