Is there a way to look at all of the values for a parameter, lets take for instance CPU for a particular server, and figure out if recent values are well above or below what would be consistent for then?  So basically, if something is 90% above or below the mean, and if it happened say in the last two hours, to report on that?

Thanks again for the help, please let me know if clarification is needed for the above, my question is a bit tricky.
