At the top there are two gauge views with spark charts in their background.
Left gauge is memory and right is CPU and totals underneath. This is meant as a quick cluster wide resource overview on the node level.
Pod CPU shows the avg and current cpu utilization percentage per pod.
System Pod CPU, this is all the "system" pods like kubedns, weave, node-exporter, it should under normal conditions be flat and low so it is somewhat greyed out.
