systor.

Lightweight Linux monitoring for DietPi, Raspberry Pi, home servers, and small VPS hosts. One Flask app, one collector, SQLite — real dashboards and alerts without the Prometheus stack.

Why not Grafana?

Built when you want observability on a box that cannot afford another 250 MB of Java and YAML.

What you get

Same GitHub-dark UI as the running app — no SPA, no Electron, no agent protocol.

⌂

Live dashboard

CPU, temp, RAM, swap, disk I/O, load, network charts, top processes, recent alerts.

◫

Apps

Host and Docker processes ranked by CPU, RAM, network, and disk.

⇄

Network

Per-interface traffic and daily / monthly / yearly usage tables.

⚡

Speed

Official Ookla CLI runs, scheduler, history, and threshold alerts.

▣

Storage

Allowed-root browser, uploads, trash/restore, duplicate scan, action password.

⚠

Sustained alerts

Threshold + duration so one spike does not wake you at 3 AM.

⚙

Settings

Telegram and Discord with test buttons, cooldowns, and live SIGHUP reload.

🔒

Public vs private

Read-only dashboard on the internet; full admin on LAN, localhost, or Tailscale.
