> I am charged with providing more insight into the functioning of the system.
That's pretty generic. Do they have certain metrics they want to see in black & white?
> I'm looking for other important and useful information I can report up to better illustrate my efforts
Then that's your answer. You just need to find out what is important & useful to them.
> I also simultaneously perform all IT related tasks in the office, which may also be important to report
Whatever you send them, be sure to word it in terms of business value. As far as providing insight - you may want to create overview docs of most ALL of the processes/systems you manage; your job will be that much more secure if the non-tech folks are truly aware of how much you do around the office. As the only IT person, you provide biz value that no other in-house employee can, AND you save them money. Show them how by providing high-level workflow diagrams of these processes.
Heck, you may even get a raise if you word it right. ; >
