✨ meminfolog(8) ✨

okay so bestie, this is a page from ClusterTools2 and it's about meminfolog — a lil script that writes down your memory info with a timestamp so you can look back later and be like "hmm 👀 what was RAM doing at 3am". It's a section 8 page (system administration, iykyk), so let's get into it 💅

🎀 NAME 🎀

meminfolog — log the meminfo with timestamp. literally that's the whole job. no cap.

🌸 SYNOPSIS 🌸

meminfolog [ logfile ]

💖 DESCRIPTION 💖

meminfolog logs the meminfo with timestamp. That's it, that's the vibe 🦋

Basically the script just puts the output of date +%F %T in front of each line for the output of cat /proc/meminfo. so every single line of your memory stats gets its own little timestamp glow-up ✨ iconic behaviour honestly.

🔥 EXAMPLES 🔥

⭐ run it every 10 minutes

To run meminfolog every 10 minutes, the crontab entry could look like this:

-01-56/10 * * * * root /usr/sbin/meminfolog /var/log/meminfo.log

🧚 rotate and compress the log

To rotate and compress the log from time to time, the logrotate entry could look like this:

/var/log/meminfo.log {
    compress
    dateext
    maxage 365
    rotate 99
    size +2M
    notifempty
    missingok
    copytruncate
}

👑 EXIT STATUS 👑

  • 0 — Successful program execution. slay, everything worked 💚
  • >0 — Usage, syntax or execution errors. 😭 something went sideways.

🦋 FILES 🦋

  • /usr/sbin/meminfolog — the script itself. the main character 👑
  • /var/log/meminfo.log — the default logfile. your go-to spot for the receipts 📝
  • /etc/cron.d/ClusterTools2 — the cron entry.
  • /etc/logrotate.d/ClusterTools2 — the logrotate entry.
