✨ TRACE-CMD-STAT(1) ✨

okay bestie, so this is a page from the libtracefs manual and it's literally about trace-cmd stat — the glow-up your terminal needs when you wanna know what's going on in your tracing (ftrace) system. it's giving "diagnostic checkup" energy and honestly? iconic. 🩺💅

🌸 NAME 🌸

trace-cmd-stat — show the status of the tracing (ftrace) system

🦋 SYNOPSIS 🦋

trace-cmd stat [OPTIONS]

💖 DESCRIPTION 💖

trace-cmd(1) stat is your little status reporter bestie — it displays the various status of the tracing (ftrace) system. the way it just spills all the tea about what's configured 😭 here's everything it shows:

  • Instances — lists all configured ftrace instances.
  • Tracer — shows up if one of the tracers (like function_graph) is active. otherwise, literally nothing is displayed. silent treatment fr.
  • Events — lists the events that are enable.
  • Event filters — shows any filters that are set for any events.
  • Function filters — shows any filters for the function tracers.
  • Graph functions — shows any functions that the function graph tracer should graph.
  • Buffers — shows the trace buffer size if they have been expanded. by default, tracing buffers are in a compressed format until they are used. if they are compressed, the buffer display will not be shown. so if you don't see it, that's why, no cap. 🫶
  • Trace clock — if the tracing clock is anything other than the default "local" it will be displayed.
  • Trace CPU mask — if not all available CPUs are in the tracing CPU mask, then the tracing CPU mask will be displayed.
  • Trace max latency — shows the value of the trace max latency if it is other than zero.
  • Kprobes — shows any kprobes that are defined for tracing.
  • Uprobes — shows any uprobes that are defined for tracing.
  • Error log — dumps the content of the ftrace error_log file. uh oh bestie, something went off 🙈

✨ OPTIONS ✨

  • -B buffer-name — display the status of a given buffer instance. lowkey you can specify it more than once to display the status of multiple instances 👑
  • -t — if -B is also specified, show the status of the top level tracing directory as well as the instance(s).
  • -o — display the all the options along with their values. if they start with "no", then the option is disabled. (so noyourvibe = off, got it 💀)
