💖 PROBE::SCHEDULER.SIGNAL_SEND 💖

okay bestie, welcome to the Scheduler Tapset corner of the SystemTap manual, page PROBE::SCHEDULER.S(3stap) — yes that's a mouthful, we're just gonna vibe with it 🫶

This one is literally all about sending a signal. That's the whole thing. She's a probe point, she's a moment in time, and she's got exactly three little values attached. Not me being obsessed with how tidy that is ✨

---

🌸 NAME 🌸

probe::scheduler.signal_send — sending a signal 📡

Like. That's it. That's her whole job description. And she ate. 💅

---

✨ SYNOPSIS ✨

probe scheduler.signal_send {}

no arguments, no parameters, no drama — just the probe point sitting there looking pretty 🎀

---

🦋 VALUES 🦋

okay so when this probe fires, you get handed three lil values. memorize them, they're the whole point bestie 💜

• name — the name of the probe point 👑 like, the identity, the label, the main character of this whole situation.
• signal_number — the signal number 🔥 as in, which signal got sent. the number itself. the digits. periodt.
• pid — the pid of the process sending the signal 🧚 notice how it says sending, not receiving. the sender. the one doing the sending. important distinction, iykyk 💀

• tapset::scheduler(3stap) — go read the rest of the scheduler tapset bestie, there's a whole family of these 🌈

fr fr, if you're here you probably already know what a signal is, but like… lowkey this probe is just a lil window into the exact moment someone hits send 📨
