W.r.t 'top' , I like ttyload, a nice tool to visualize cpu load and spikes in a
simple plotted terminal graph. I run it in a screen so i can look at it any
time by attaching to it.
screen -S myttyload? -> creates a screen called myttyload
screen -x myttyload -> attaches to it ;
ctrl+A, then d -> detaches from screen without exiting.
