wspy – instrumentation: ftrace and ptrace — 1 Comment

  1. I have now added basic support to create a process tree from ptrace(2) events that follow a child process.

    Along the way, I’ve added an option –processtree-engine with two options: ftrace and ptrace to pick between these two mechanisms.

    At this point, the ptrace engine doesn’t have as much information such as the elapsed times of processes since this isn’t immediately given. However, I do have the potential for getting quite a bit more other information by going to /proc/[pid]/* files at the process exit.
