Some advanced BCC topics

Timely and relevant article, thank you, love to see more. The previous article helped me the same day it was published with a kernel performance evaluation I was doing. I ended up running more than 6k KVM guests on a huge machine and got scheduling latency data using BCC. I spent most of my work time building LLVM for the linux distro I had to use, which is a variant of fedora. Once that task was finished, the hardest thing I had to do was to decide which particular tool of many was best to use. If anyone is on the fence because of the LLVM requirement, I would say go ahead, its worth it.
