This looks really polished and definitely a great idea. I can see why you chose Ruby for the scripting of the monitors, being able to evaluate that code in a predefined binding can be quite powerful, especially with the aid of helpers being pre-defined as well.
Why not a full ruby stack, or was the "live" scripting done after the initial inception?
