💖 LLSTAT(8) — the lustre stats bestie 💖

okay so real talk, this page lives in the Lustre Configuration Utilities section of the manual (that's the 8, iykyk), and it's genuinely one of my faves because it just… shows you the numbers. live. every second if you want. slay.

✨ NAME ✨

llstat — print Lustre statistics 💅

🌸 SYNOPSIS 🌸

llstat [-c] [-g] [-i INTERVAL] STATS_FILE

🦋 DESCRIPTION 🦋

so llstat can display statistics from any of several lustre stats files that share a common format, and it refreshes them every INTERVAL seconds. that's the whole vibe. it just keeps printing, over and over, like a group chat you refuse to mute.

to stop the stats from printing, hit Ctrl+C. that's it. no drama.

🎀 OPTIONS 🎀

  • -c — clear the stats file first. wipe it. fresh start energy. 🧼
  • -i INTERVAL — polling period, in seconds. how often bestie checks back in.
  • -g — graphable output format. for when you wanna make it a lil picture. 📈
  • -h — display help information. the classic "help me help you".
  • STATS_FILE — either the full path to a stats file, or the shorthand: mds or ost. yes, literally just those two words if you're feeling lazy, and honestly, valid. 👑

🌈 FILES 🌈

here's the whole lil family of stats files it knows about:

  • llite.*.stats
  • lwp.*.stats
  • mdc.*.stats
  • obdfilter.*.stats
  • osc.*.stats
  • osd-ldiskfs.*.stats
  • osp.*.stats
  • ldlm.services.*.stats
