PLOT-LLSTAT(8)

✨ PLOT-LLSTAT ✨

okay bestie, so this is the manual page for plot-llstat, and it lives in section 8 of the Lustre Configuration Utilities manual 💖 if you're out here reading man 8 plot-llstat, you're in exactly the right place, and yes we're gonna make sense of every single line together 🫶

🌸 NAME 🌸

plot-llstat — plot Lustre statistics ✨ (yes that's literally it, she does one thing and she does it fabulously)

---

🎀 SYNOPSIS 🎀

plot-llstat RESULTS_FILENAME [PARAMETER_INDEX]

---

🦋 DESCRIPTION 🦋

so the tea is this: the plot-llstat script generates a csv file and instructions files for gnuplot, all from the output of llstat 💅 and since llstat is generic in nature, plot-llstat is also a generic script — no cap, she doesn't care what you threw at her, she'll work with it.

parameter_index can be:

• 1 — count per interval
• 2 — count per second (the default, so if you don't say anything she assumes this one)
• 3 — total count

now, the way the plot-llstat script works is it creates a dat (csv) file using the number of operations specified by the user 👑 number of operations equals number of columns in the csv file. and the values in those columns are equal to the corresponding value of the PARAMETER_INDEX parameter from the output file. literally 1:1, she's that consistent 💖

plot-llstat also creates a .scr file that contains instructions for gnuplot to plot the graph 🌈 and after generating the .dat and .scr files, plot-llstat invokes gnuplot to display the graph. so she doesn't just hand you the homework — she goes and presents it for you too 😭 iconic behaviour honestly.

🧚 EXAMPLES 🧚

look at her go:

llstat -i2 -g -c lustre-OST0000 > log
plot-llstat log 3

first line makes the log, second line turns that log into a whole graph moment with parameter index 3 🔥
