Hey Richard,
I wouldn't think about it that way. That can get you into trouble.
For example, let's say you're monitoring environmental variables such as
temperature. Do you really care what the absolute temperature is? 30, 40
or 50 degrees, etc? Obviously, a variable such as temperature can go up or
down. What you care about is whether the temperature has changed ie, Delta,
alot in a short period since that might indicate a problem. Same for cpu
utilization.
On the other hand, there are variables such as memory in use which are
finite in nature. So, you may want to know if your router has 32MB of
memory when memory is use reaches 24MB, an absolute value, since at that
point, you may want to consider adding more memory to your router.
HTH, Tim
