CPU utilization charts for the z/VM large memory tests explained

To help you understand the CPU utilization charts produced from our large memory test runs, we have provided a sample chart with an explanation.

In the charts in this report, the CPU utilization values are always normalized in a way that 100% means one CPU is fully utilized.

The CPU utilization charts in the report look like Figure 1.

The CPU utilization charts show the utilization for the z/VM® LPAR by a line with triangle symbols. The details of how the z/VM guests use the CPUs (total CPU time accounted for the guests) are shown by stacked bars, which should sum up to the z/VM utilization without the CP related CPU part, so it is always a little lower than the z/VM LPAR utilization. If the CPU utilization from a guest in the legend is not visible, that means it is too low to display.
