It has less than 0.1% of cpu overhead and can even gather some of the less common statistics such as lustre file system and infiniband. Naturally it does all the 'standard' ones as well. All in one tool!

I may have to alias top to atop. After reading your note about per-process network/disk information, I was particularly excited. The fact that you have to patch your kernel for it however is ugly. It really makes me wonder why it's taken so long for simple counters like this to be merged into the mainstream Linux kernel. I bet we see SystemTap go mainstream and have atop ported to it before that happens. SystemTap is already very usable as is. Thanks for the tip on atop! I may have to alias top to atop.
