FUMON(1)

💅 FUMON(1) — like, the Failed Units Monitor, bestie ✨

okay so real quick: this is a page from the General Commands Manual and honestly? it ate. it's short, it's iconic, it's giving "i do one thing and i do it flawlessly." let's get into it 🫶

🌸 NAME 🌸

FUMon — the Failed Units Monitor. that's it. that's the whole personality. she monitors failed units. she's very good at it. periodt 💅

---

✨ SYNOPSIS ✨

fumon

no flags. no arguments. no drama. you just run fumon and she goes to work, main character energy only 🔥

---

🦋 DESCRIPTION 🦋

so here's the vibe: fumon watches for user units entering failed state, and when one does? she sends notifications via notify-send. she's basically your little systemd lookout, sitting there quietly, minding her business, until something breaks and then — boom — you get told about it. no cap, that's genuinely useful 😭💖

the service itself is managed by the user unit fumon.service, which is wanted by graphical-session.target. so she shows up right along with your graphical session, like a bestie who always arrives at the party at the exact right time 🎀

⚠️ heads up: if it is not enabled by default, you gotta go turn it on yourself. she's not gonna enable herself, queen.

enable and start it with:

systemctl --user enable --now fumon.service

that's the whole ritual. enable so she comes back after every login, --now so she starts immediately instead of making you log out like some kind of peasant. slay 🌈
