All right just though I would throw this out as a suggestion.
So I have found the wa parameter in top to be a very useful metric on VM host machines. The wa parameter is the time spent waiting for I/O operations; which most often means if you get a high wa value, your hard disks are thrashing. I just figure this would be an easy graph to add to the Local System Status page on the homepage, the one with the graphs for CPU usage, Memory usage, etc. This would make it easy to see at a glance if your hard drives are under heavy usage, much like the CPU and Memory graphs do.
Thanks!
