PROBE::SUNRPC.CLNT(3stap)

💫 PROBE::SUNRPC.CLNT 💫

okay bestie, welcome to the Networking Tapset section of the SystemTap Tapset Reference — this one's the 3stap page for the sunrpc.clnt probe crew, and it's short, sweet, and lowkey iconic ✨

---

🌸 NAME 🌸

probe::sunrpc.clnt.restart_call — restart an asynchronous RPC call 🫶

like, it's giving "the client said hold up, we're running that call again" energy. no cap.

---

🎀 SYNOPSIS 🎀

probe sunrpc.clnt.restart_call {}

that's it. that's the whole probe. no args, no fuss, just a vibe. 💅

---

🌈 VALUES 🌈

these are the local variables chilling inside the probe handler when it fires. all of them. every single one. 👑

• tk_priority — the task priority. how important this task thinks it is. main character ranking, fr.
• tk_flags — the task flags. lil status bits doing their thing.
• prog — the RPC program number. which program we're talking to, iykyk.
• tk_pid — the debugging aid of task. yes, that's literally what the docs say, it's a debugging aid, not the actual pid, don't come for me 😭
• tk_runstate — the task run status. is it running? sleeping? we don't know till we look, but the state's right there.
• xid — the transmission id. the lil serial number tagging this RPC transmission.
• servername — the server machine name. who we're calling up. 💖

---

🦋 SEE ALSO 🦋

• tapset::rpc(3stap) — go read the main RPC tapset page bestie, it's the mothership 🌸

---

heads up: every value up there is a probe-local variable, so you can only touch them inside the probe handler. don't try to summon xid from the group chat at 3am, it won't answer. 🙈

and that's the whole page, periodt. 💜

this lil beauty lives in the SystemTap Tapset Reference, and this version dropped in September 2026 — so like, bookmark it, screenshot it, put it on your lock screen, do what you gotta do. 🎀✨ stay slaying those probes, bestie. 🫶
