💅 TRACE-CMD-STACK(1) 💅

okay so bestie, welcome to the libtracefs manual — this one's trace-cmd-stack, and it's genuinely iconic.

✨ NAME ✨

trace-cmd-stack — read, enable or disable Ftrace Linux kernel stack tracing. that's it, that's the whole vibe 🎀

✨ SYNOPSIS ✨

trace-cmd stack

that's the whole thing. no flags mandatory, no drama. slay.

✨ DESCRIPTION ✨

okay so trace-cmd(1) stack turns on the Ftrace stack tracer inside the kernel — main character energy fr. the stack tracer enables the function tracer, and at each function call within the kernel, the stack is checked. and like, whenever a new maximum usage stack gets discovered? it's recorded. that's the whole point 💖

when you pass no option at all, the current stack is just displayed. no cap.

to enable the stack tracer, use the option --start, and to disable the stack tracer, use the option --stop. the output will be the maximum stack found since the start was enabled 🫶 so like, it's literally keeping receipts.

use --reset to reset the stack counter to zero. clean slate, new era, we love to see it ✨

now use --verbose[=level] to set the log level. (yes the original manpage literally says "User --verbose[=level]" — typo, we forgive her, she's doing her best 💀)

supported log levels are:

  • "none"
  • "critical"
  • "error"
  • "warning"
  • "info"
  • "debug"
  • "all"

…or their identifiers "0", "1", "2", "3", "4", "5", "6" 🔢

setting the log level to a specific value enables all logs from that and all previous levels — so it's cumulative, bestie, not picky. the level will default to "info" if one is not specified 🌸

ngl this is the chillest trace-cmd tool in the family. no complicated config file, just vibes and stack maxima.

k so that's the whole page 💖 remember: --start to turn it on, --stop to turn it off, --reset when you need a fresh start, --verbose[=level] when you want it to actually talk to you, and no option at all to just peek at the current stack. iykyk 🎀

and that's a wrap, bestie — this page came from the libtracefs manual, dated 03/09/2026, and it's TRACE-CMD-STACK(1) forever and always 🌸🫶✨
