I use vmstat and top together to determine if a system is (too) busy or not. vmstat gives a good indication about the amount of disk IO (both regular IO and swap), and top sorted by cpu or memory shows which processes are responsible for the numbers. You as a human can interpret what you see. I don't think software should do anything with the load average, as it does not reflect the actual usage of the hardware.
