MUNIN-NODE(1)

💖 MUNIN-NODE(1) 💖

okay bestie, gather round, because today we're talking about munin-node — the little daemon that reports stats on your system's performance. it's from the User Contributed Perl Documentation section of the manual, and honestly? she's iconic. let's get into it 🫶

---

✨ NAME ✨

munin-node — a daemon that gathers information in cooperation with the main Munin program. that's the whole vibe. 💅

---

🌸 SYNOPSIS 🌸

munin-node [--options]

that's it. that's the whole invocation. slay.

---

🦋 DESCRIPTION 🦋

so munin-node is a daemon — a little background bestie — whose entire job is reporting statistics on system performance. 📊

but here's the thing: she doesn't actually produce those stats herself. no no. she's more of a manager, a girlboss delegating to her team. the real work gets done by a bunch of plugins, and those plugins are responsible for:

• gathering the data they need, and
• describing how that data should be graphed.

fr fr, munin-node does little more than:

1. fielding requests from the Munin master 👑
2. running the appropriate plugins
3. returning the output they produce

that's her whole main character arc. and she ate. ✨

---

💅 OPTIONS 💅

• --config <configfile> — use file as the configuration file. default is /etc/munin/munin-node.conf. [that's the default, bestie]
• --[no]paranoia — only run plugins that are owned by root, and check the permissions too. default is --noparanoia. (yes, she has a paranoia mode. we love a cautious queen 🎀)
• --help — view this help message. the classic. the icon. 🫶
• --[no]debug — view debug messages. warning: this can be very verbose. like, very. brace yourself. 😭
• --[no]pidebug — plugin debug. this sets the environment variable MUNIN_DEBUG to 1 so that plugins may enable debugging. default is --nopidebug.

---

🎀 FILES 🎀

here's where she keeps all her stuff:

/etc/munin/munin-node.conf
/etc/munin/plugins/*
/etc/munin/plugin-conf.d/*
/var/run/munin/munin-node.pid
/var/log/munin/munin-node.log

config, plugins, plugin configs, her pid, her log. a whole organized girlie. ✨
