PROBE::LINUXMIB.LI(3stap)

✨ NAME ✨

probe::linuxmib.ListenOverflows — bestie, this one counts how many times a listen queue straight up overflowed 😭 like the queue said "no more room, I'm full" and that's the tea 💅

It lives in the SNMP Information Tapset (section 3stap), so you already know it's giving systemtap tapset realness 🎀

---

🌸 SYNOPSIS 🌸

probe linuxmib.ListenOverflows {}

no args, no drama, just the probe name and some curly braces, iconic 💖

---

🦋 VALUES 🦋

• op — the value you're adding to the counter. lowkey the default here is just 1 👑
• sk — a pointer to the struct sock that's being acted on. literally a whole pointer, be careful with it 🫶

---

⭐ DESCRIPTION ⭐

okay so here's the vibe: the packet that skb points to gets filtered by the function linuxmib_filter_key 🧚 and if the packet passes that filter, it gets counted in the global ListenOverflows counter. that's it, that's the whole job ✨

and in case you were wondering what that counter even is — it's equivalent to SNMP's MIB LINUX_MIB_LISTENOVERFLOWS 💀 so yeah, this probe is the little birdie whispering overflow stats into your SNMP world 🌈
