Beszel

Lightweight metrics for your hosts and containers — CPU, memory, disk, network · https://bz.fmm.house

What it's for

Beszel is a small, fast dashboard for keeping an eye on your servers. Each host runs a tiny agent that reports CPU, memory, disk, and network usage, and Beszel graphs it over time. Drill into any system to see its history, and open a btop-style per-container view to find which container is eating resources. It's the "how's the box doing?" panel — light enough to leave running all the time.

Getting in

  • Open: https://bz.fmm.house — on the home Wi-Fi/LAN, or from anywhere with Tailscale connected.
  • Sign in: admin-oriented. Log in with your Beszel account.

Warning

Android login can silently fail. If your password manager autofills the login form on Android, the form may not submit — nothing happens when you tap the button (a known upstream Beszel bug). Work around it by using Firefox on mobile, or sign in through the PocketBase admin login at /_/ (https://bz.fmm.house/_/) instead.

How to use it

Read the dashboard

The home view lists every connected system with live CPU, memory, disk, and network at a glance, plus an up/down indicator. Green and low means healthy; a system pegged high or gone offline stands out. It refreshes on its own, so you can leave it open on a second screen.

Drill into a system

Click a host to open its detail page. Here you get time-series graphs — CPU load, memory used, disk usage and I/O, network throughput — with a selectable time range so you can zoom from the last hour out to weeks. This is where you spot trends: a slow memory climb, a disk filling up, a nightly CPU spike from a backup job.

The container view

On a host that runs Docker, Beszel shows a btop-style per-container breakdown — each container's CPU, memory, and network side by side. It's the quickest way to answer "what's using all the RAM?" — sort by the resource you care about and the culprit is right there, without SSHing in to run docker stats yourself.

Tips

  • Set the time range to match the question. A short window shows the current spike; a long window reveals slow leaks and creeping disk usage.
  • Container view beats guessing. When a host looks busy, jump straight to its container breakdown instead of eyeballing the host graph.
  • Bookmark /_/ — the PocketBase admin login is your reliable way in when the normal login misbehaves on mobile.
