I prefer the more deep dive approach presented by brendan gregg http://www.brendangregg.com/ebpf.html

It made me cringe reading the first line "The Linux kernel is an abundant component of modern IT systems". Come on guys, it's the kernel, there is one of them per system.

I liked the link to Load Averages on his site [0] - including the heroric tale of finding the source of the original patch that changed it to include more than just processes in CPU wait state.

Every time I come across Brendan Gregg's work I'm blown away. And I come across his work a lot! (It also brings a semi-patriotic tear to my eye to hear his aussie twang)
