PROBE::NFS.PROC.(3stap)

💅 PROBE::NFS.PROC.LOOKUP — okay bestie, let's get into it

So this page lives in the Network File Storage Tapsets manual, and it's a SystemTap tapset probe page. Buckle up, it's short but it's iconic. 🦋

---

✨ NAME ✨

probe::nfs.proc.lookup — no cap, what this does is: the NFS client opens or searches a file on the server. That's the whole vibe. 👑

---

🌸 SYNOPSIS 🌸

probe nfs.proc.lookup {}

That's it. No arguments, no drama, just a probe with an empty body waiting for you to fill it with your little scripts. 💖

---

🎀 VALUES 🎀

These are all the things you can peek at inside the probe, and honestly they ate:

• server_ip — the IP address of the server. Like, who are we even talking to here. 🌐
• version — the NFS version. Because version matters, always. 💅
• bitmask1 — a V4 bitmask representing the set of attributes supported on this filesystem. Yes queen, bits.
• bitmask0 — also a V4 bitmask representing the set of attributes supported on this filesystem. And yeah, it's literally the same description as bitmask1 — that's not me being lazy, that's just what the page says. Two bitmasks, both doing their thing. 🫶
• prot — the transfer protocol. The way the data gets moved around. ✨
• filename — the name of the file which the client opens/searches on the server. The main character of this whole operation, honestly. 🌟
• name_len — the length of the file name. Gotta know how long the name is, that's just good manners. 📏

---

🦋 SEE ALSO 🦋

• tapset::nfs_proc(3stap) — go read this one too, it's the parent tapset and it's lowkey required reading. 💜

---

Just a lil heads up bestie: the two bitmask descriptions on this page are word-for-word identical in the original. I'm not going to invent a difference that isn't there — if you need to know which is which, the tapset source is your friend. 🙈

---

That's the whole page, fr fr. Go forth and probe. 💖✨

Signing off with the official tea: this is from the SystemTap Tapset Reference, version noted as Ver, dated September 2026. Sending you all the good probe vibes, bestie. 🎀👑🌈
