💖 diskdevstat — like, the manual page bestie 💖

okay so this is diskdevstat(8) from section 8 of the manual, and the vibe is recording harddisk activity. yes queen, we're spying on your disks (lovingly).

✨ NAME ✨

diskdevstat — a tool for recording harddisk activity 🦋

✨ SYNOPSIS ✨

diskdevstat [update interval] [total duration] [display histogram]

✨ DESCRIPTION ✨

so diskdevstat is literally just a lil systemtap script — a simple one, no cap — and what it does is record the harddisk activity of your processes and then show you the stats for read/write operations. it's giving disk detective energy 🔍💅

the three lil arguments 🎀

  • update interval — sets the sampling interval, in seconds. how often we peek at the disk, basically.
  • total duration — sets the total measurement time, in seconds. how long we're doing this whole thing for.
  • display histogram — if this parameter is present (like, if you actually pass it), the histogram gets shown at the end of the measurement. present = histogram. iconic. 📊✨
ngl bestie, that's the whole tool. three args, one job, and she does it. periodt.
