The CPU utilization (including system, user, I/O wait and other), is normalized to 100%, and is calculated as the number of CPU seconds used, divided by the number of CPUs, divided by the number of seconds in the time frame. You can view the CPU utilization of a specific server or of the Tier (if you select All servers).

The gauge shows the following:

Breach LevelGauge
0 - 60% utilizationShows as normal
61 - 80%Shows as a warning level.
81 - 100%Shows as critical.
