PROBE::NFSD.PROC(3stap)

💖 PROBE::NFSD.PROC.LOOKUP 💖

okay bestie, welcome to the probe::nfsd.proc.lookup page from the Network File Storage Tapsets manual — section 3stap, so you already know it's giving systemtap tapset energy ✨

🌸 NAME 🌸

probe::nfsd.proc.lookup — NFS server opening or searching for a file for client

like… the server is out here looking for a file on behalf of a client. very main character of it, honestly 🫶

---

✨ SYNOPSIS ✨

probe nfsd.proc.lookup {}

no args, no drama, just vibes 💅

---

🦋 VALUES 🦋

every one of these is a thing this probe hands you. do not skip any, they're all iconic in their own way:

• proto — transfer protocol 💌
• client_ip — the ip address of client 📍
• gid — requester's group id 👯
• filename — file name 📄
• fh — file handle of parent dir (the first part is the length of the file handle) 🔑
• uid — requester's user id 🪪
• filelen — the length of file name 📏
• version — nfs version 🔢

lowkey obsessed with how fh comes with a built-in length prefix. the first part is literally the length of the file handle. not a vibe, it's a fact, fr fr.
