PROBE::IPMIB.FORWD(3stap)

✨ PROBE::IPMIB.FORWD ✨

okay bestie, welcome to the SNMP Information Tapset section of the SystemTap Tapset Reference — this page is probe::ipmib.ForwDatagrams and it's lowkey iconic 💅

---

🦋 NAME 🦋

probe::ipmib.ForwDatagrams — count a forwarded packet, periodt 💖

---

🌸 SYNOPSIS 🌸

probe ipmib.ForwDatagrams {}

that's it. that's the whole probe. no arguments, no drama, just vibes ✨

---

🎀 VALUES 🎀

the two lil things you get handed when this probe fires:

• skb — a pointer to the struct sk_buff that's being acted on, aka the packet in question 🫶
• op — the value that gets added to the counter. default is 1, so if you don't touch it, every hit just bumps the tally by one, no cap 🙈

---

💖 DESCRIPTION 💖

so here's the tea ☕ the packet that skb points at gets run through the filter function ipmib_filter_key. if the packet passes that filter, it gets counted in the global ForwDatagrams counter — which is literally the same thing as SNMP's IPSTATS_MIB_OUTFORWDATAGRAMS, iykyk 👑

tl;dr: filter check first, then count. if it doesn't pass, no counting for you 😭
