Hi Scott -
A little context might help us help you ;)
Are you talking about operational metrics? (i.e. How much work is my system(s) doing?, How fast are my journals growing? etc.) or are you talking about "What's Stakeholder X's traffic today and of what type?"
There are some MANY things available, it becomes a question of what is the purpose of the measurements so we can figure out where to start getting meaningful values for your business need.
