Shows the CPU usage of each node's machine, for example 37%. The usage is measured on the node itself each time the monitor refreshes, as the mean of three one-second samples, so a single short spike does not decide the value. It is still a snapshot and not an average over the whole interval. Usage at or above a configurable percentage (default 99%) is shown in Jenkins' warning style.

Hover over the value to see more detail, for example System: 37% (peak 91%) • JVM: 2%:

Inside a container, the usage is relative to the container's CPU limit. If the Java virtual machine cannot measure the usage, N/A is shown.
