🎀 NAME 🎀

nmon — the systems administrator, tuner, benchmark tool 💅 (also known as section 1 of the User Commands manual, iykyk)

💖 DESCRIPTION 💖

okay so this manual page is a lil quick rundown of the nmon command, bestie. and lowkey a fun fact: this page was written specifically for the Debian distribution because the original program doesn't ship with a manual page at all 😭 iconic of Debian honestly.

nmon is a systems administrator, tuner, benchmark tool 🫶 and the way it can show you EVERYTHING:

  • CPU
  • memory
  • network
  • disks (mini graphs or numbers, your choice bestie)
  • file systems
  • NFS
  • top processes
  • resources (Linux version & processors)
  • and on Power micro-partition, information 👑

it's giving "one tool, all the vibes" fr fr.

✨ OPTIONS ✨

so nmon follows the usual GNU command line syntax, with long options starting with two dashes (-) 💀 (yes that's what it says, don't come for me).

nmon [-h] [-s <seconds>] [-c <count>] [-f -d <disks> -t -r <name>] [-x]

a summary of the options is down below, no cap:

  • -h — FULL help information 🫶

and for Interactive-Mode: read the startup banner and type: "h" once it's running 🎀 For Data-Collect-Mode, that's the -f one 👇

  • -f — spreadsheet output format 🔥 [note: default -s300 -c288] and it's optional bestie
  • -s <seconds> — how long between refreshing the screen ⏱️ [default 2]
  • -c <number> — how many refreshes you want 🌸 [default millions] — yeah. millions. she's not subtle.
  • -d <disks> — to increase the number of disks 💾 [default 256]
  • -t — spreadsheet includes top processes 👑
  • -x — capacity planning 📊 (15 min for 1 day = -fdt -s 900 -c 96)
⚠️ heads up bestie: that -f default is -s300 -c288, so if you just yeet -f on its own, that's the vibe you're getting. know before you go 💅
