LLJOBSTAT(8)

💅 LLJOBSTAT — it's giving top jobs, bestie

okay so this one lives in the Lustre Configuration Utilities family (section 8 of the manual, for the sysadmin girlies who live in the terminal ✨), and it's fr fr one of my faves.

✨ NAME ✨

lljobstat — display top jobs and statistics 🎀

---

🌸 SYNOPSIS 🌸

llobdstat [-c|--count COUNT] [-i|--interval INTERVAL] [-n|--repeats
          REPEATS] [-m|--mdt] [-o|--ost] [--param PARAM] [--fullname]
          [--no-fullname]

not me noticing the llobdstat in there — yes bestie I copied it character for character exactly like the original, we do not edit the sacred text 💀

---

👑 DESCRIPTION 👑

So what does she actually do? lljobstat reads and parses the job_stats files on the local node, sums up the operations of each job, and shows you the top jobs. Iconic behaviour, truly. 🔥

Then she repeats that — for however many times you asked for, or forever and ever — with the interval you gave her. Main character energy that never clocks out.

Type Ctrl+C to stop printing. 🛑

🦋 Abbreviations 🦋

lljobstat shows abbreviations of operation names, and here's the whole decoder ring:

ops: total number of operations
cl: close,      cr: create,     dt: destroy,    fa: fallocate, ga: getattr
gi: get_info,   gx: getxattr,   ln: link,       mi: migrate,   mk: mkdir
mn: mknod,      mv: rename,     op: open,       pa: prealloc,  pu: punch
qc: quotactl,   rd: read,       rm: rmdir,      sa: setattr,   si: set_info
st: statfs,     sx: setxattr,   sy: sync,       ul: unlink,    wr: write

no literally, screenshot it, put it in your notes app, iykyk 📝

💖 OPTIONS 💖

• -c, --count COUNT — how many top jobs get listed. Default 5.
• -i, --interval INTERVAL — interval in seconds before she lists the top jobs again. Default 10.
• -n, --repeats REPEATS — how many times to repeat. Default is unlimited, so like… she'll go forever unless you tell her otherwise 😭
• -m, --mdt — get data from only job_stats of MDTs. MDT girlies, this one's for you 💜
• -o, --ost — get data from only job_stats of OSTs. OST girlies, your turn 🌈
• --param PARAM — get data from only PARAM path. For example, "*.lustre-*.job_stat".
• --fullname — show the full name of operations. Default is no.
• --no-fullname — show the abbreviated name of operations.
• -h, --help — print the help message. (Always a slay, never a fail. 🫶)

🌟 EXAMPLES 🌟

look at her go:

# lljobstat -n 1 -c 3
---
timestamp: 1665623345
top_jobs:
- rm.0:            {ops: 99, cl: 32, ul: 16, rm: 16, ga: 19, st: 16}
- touch.500:       {ops: 48, op: 8, cl: 8, mn: 8, ga: 8, sa: 16}
- dd.0:            {ops: 38, op: 4, cl: 4, mn: 1, ga: 1, sa: 3, gx: 3, wr: 19, pu: 3}
...

like… rm.0 ate that round, no cap. 💀✨
