RV-MON-STALL(1)

okay bestie, pull up a chair</p> — this is rv-mon-stall, straight out of the General Commands Manual, and it's literally the cutest little task-watcher you ever met. 💅

✨ NAME ✨

rv-mon-stall — the Stalled task monitor 🦋

✨ SYNOPSIS ✨

rv mon stall [OPTIONS]

✨ DESCRIPTION ✨

So the stalled task monitor — stall for short, iykyk — is a sample per-task timed monitor. Its whole vibe? It checks whether tasks actually get scheduled within a defined threshold once they're ready. If they're ready and just… sitting there? Yeah, that's a stall, and this monitor is the one noticing. 👀

Wanna go deeper? The kernel docs are right here:

<https://docs.kernel.org/trace/rv/monitor_stall.html>

✨ OPTIONS ✨

• -h, --help — prints the monitor's options and the list of available reactors. Basically the "hey what can u even do" button. 🎀
• -r, --reactor reactor — turns on the reactor. Not sure which reactors exist? Bestie, run -h and it'll show you the whole list. ⭐
• -s, --self — when you're tracing (that's with -t), this also prints the events that happened during the rv command itself. 🪞 Heads up tho: if the rv command generates too many events of its own, the tool might end up busy processing nothing but its own events. So… iconic, but chaotic. 💀
• -t, --trace — traces the monitor's events and errors. 🔥
• -v, --verbose — prints debug messages. For when u wanna know everything. 🙈
