Is there a diagram that shows how the various performance tools such as ip, netstat, perf, top, ps, etc. interact with the various subsystems within the Linux kernel?

I came across this diagram which shows exactly this.
In the above you can see where tools such as strace, netstat, etc. interact with the Linux kernel's subsystems. I like this diagram because it succinctly shows where each tool latches on to the Linux kernel, which can be extremely helpful when you're first learning about all the tools and their applications.

It's missing `ltrace`, but nice diagram. – abligh Mar 02 '14 at 21:29

`ltrace` is there in the original png ('Source' at the bottom) – thameera Mar 03 '14 at 07:26
