"Sites and KUtrace met my 33-year-old one-second challenge." Donald Knuth's praise for Richard Sites' Stanford Seminar "Making the Invisible Visible: Observing Complex Software Dynamics" and in reference to the low-overhead open-source software tool, KUtrace. What is KUtrace? KUtrace (Kernal-User Trace) is a Linux-based software facility that captures and timestamps every transition between user-mode and kernel-mode execution—every system call and return, interrupt and return, trap and return, and context switch. The CPU overhead is under 0.5% when doing 200,000 events per second per CPU core, so it is about 10x faster than a tool such as ftrace. Recording is into a pre-reserved kernel trace buffer of several megabytes. Understanding Software Dynamics teaches you how to build the low-overhead KUtrace tool to record for any server what kernel or user code is executing on each CPU core every nanosecond—all programs, all operating system code, all interrupt handling, all idle loops, etc.
