If I remember right, this is a counter of CPU seconds. The problem you get is when you have multiple CPUs and need to normalise this to a percentage.... Graph it as a normal counter, which results in a calculated seconds per second, and use a Factor[] of 100 to give you a percentage on a single-CPU system. If you have a dual CPU system, use a factor of 50 (100/cpus) and so on, and set ShortLegend[] to %.
