What do the top numbers mean?

hello Mark,

sh proc cpu history shows total average and peak cpu usage so you cannot find what process(es) caused the spikes

you should use sh proc cpu sorted just after the spike to find out the problem

the top numbers are labels in vertical for the values on the graph

1

= 11

hope to help

Giuseppe
