CPU utilization charts explained

Edit online

The charts in this publication that depict the CPU utilization values are always normalized in a way that 100% means that one CPU is fully utilized.

This chart shows the CPU utilization values for client scaling. — Figure 1. Example CPU utilization

In 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 CPU is shown with stacked bars, which should sum up to the z/VM utilization without the CP related CPU part, so it is always a little bit smaller than the z/VM LPAR load. If the CPU load from a guest in the legend is not visible, that means it is too small to display.
