PROBE::SCHEDULER.P(3stap)

πŸ’… PROBE::SCHEDULER.P β€” the Scheduler Tapset one, bestie

okay so literally welcome to the Scheduler Tapset corner of the SystemTap reference, and today's main character is a probe that catches the scheduler the exact moment it's about to start waiting on a process 🫢


✨ NAME ✨

probe::scheduler.process_wait β€” Scheduler starting to wait on a process πŸ¦‹

like. it's the probe that slides in right when the scheduler is like "ok bestie i'm gonna wait on this process now" and taps you on the shoulder about it. no cap.


πŸŽ€ SYNOPSIS πŸŽ€

probe scheduler.process_wait {}

that's it. that's the whole thing. no args, no drama, just the probe point sitting there looking iconic πŸ’…


🌸 VALUES 🌸

these are the lil variables you get handed when the probe fires. use them, they're yours now:

  • name β€” the name of the probe point 🏷️ (yes, the probe point tells you its own name, self-aware king behavior)
  • pid β€” the PID of the process the scheduler is waiting on πŸ‘€ like the actual process id of whoever the scheduler is sitting around waiting for
fr fr, that pid is the whole point of this probe. that's the tea. that's the lore. πŸ“
