hostmonitor

A lightweight host monitoring dashboard built with SvelteKit + Node.js.

Architecture

• Frontend: SvelteKit (Svelte 5, TailwindCSS)
• Backend: SvelteKit server routes (+server.ts) — no separate backend process
• Metrics collection: systeminformation npm package
• Runtime: Node.js (via @sveltejs/adapter-node)

The app is a single Node.js process serving both the UI and the /api/hostinfo endpoint.

Endpoints

Metrics collected

• CPU: physical/virtual core count, usage %, load averages, temperature
• Memory: total, free, cached, swap
• Disk: total/free on /
• OS: hostname, uptime, platform, kernel version, boot time
• Network interfaces list
• Running processes count
• Container detection
