A line graph like that isn't easy to render or interpret once you have many hosts. Take the example in the blog post I linked: utilization of 300 host (5,312 CPUs). Here's the data visualized as a line graph: http://www.brendangregg.com/HeatMaps/lines-allcpus-image.png http://www.brendangregg.com/HeatMaps/lines-allcpus-image.png Here it is as a heatmap: http://www.brendangregg.com/HeatMaps/cpu-utilization-heatmap-600.png http://www.brendangregg.com/HeatMaps/cpu-utilization-heatmap... Which one conveys more information?
