💖 NAME 💖

okay so bestie, this is the STACKCOLLAPSE-PERF.PL(1) manual page, and it’s for stackcollapse-perf.pl version 1.0 — yes, the whole thing is giving “manual page for stackcollapse-perf.pl 1.0” energy 💅✨.

✨ DESCRIPTION ✨

okay so the description starts off iconic and a little unhinged: it literally opens with Unknown option: help 😭 and then gives you the usage line:

USAGE: ./stackcollapse-perf.pl [options] infile > outfile

like, hello?? infile goes in, outfile comes out, no cap 🫶.

🎀 the options menu 🎀

  • --pid — include PID with process names [1] 🦋
  • --tid — include TID and PID with process names [1] 🌸
  • --inline — un-inline using addr2line 🧚
  • --all — all annotations (--kernel --jit) 🔥
  • --kernel — annotate kernel functions with a _[k] 👑
  • --jit — annotate jit functions with a _[j] 💅
  • --context — adds source context to --inline ✨
  • --srcline — parses output of 'perf script -F+srcline' and adds source context ⭐
  • --addrs — include raw addresses where symbols can't be found 💀
  • --event-filter=EVENT — event name filter 🎀

🫶 footnote [1] 🫶

perf script must emit both PID and TIDs for these to work; eg, Linux < 4.1:

perf script -f comm,pid,tid,cpu,time,event,ip,sym,dso,trace

for Linux >= 4.1:

perf script -F comm,pid,tid,cpu,time,event,ip,sym,dso,trace

If you save this output add --header on Linux >= 3.14 to include perf info 🍓.

mwah 💋 this has been the STACKCOLLAPSE-PERF.PL(1) page for stackcollapse-perf.pl version 1.0, dated November 2022 — periodt, go collapse some stacks responsibly 🫶🌈
