Features ​

  • Lightweight: Smaller and less resource-intensive than leading solutions.
  • Simple: Easy setup with little manual configuration required.
  • Alerts: Configurable alerts for most metrics. Supports many notification services.
  • Docker stats: Tracks CPU, memory, and network usage history for each container.
  • Network monitoring: Monitor response time and interruptions directly from agents.
  • S.M.A.R.T.: Disk health data and notifications on drive failure.
  • Multi-user: Users manage their own systems. Admins can share systems across users.
  • OAuth / OIDC: Supports many OAuth2 providers. Password auth can be disabled.
  • Automatic backups: Save to and restore from disk or S3-compatible storage.

Architecture ​

Beszel consists of two main components: the hub and the agent.

  • Hub: A web application built on PocketBase that provides a dashboard for viewing and managing connected systems.
  • Agent: Runs on each system you want to monitor and communicates system metrics to the hub.

Supported metrics ​

  • CPU usage - Host system and Docker / Podman containers.
  • Memory usage - Host system and containers. Includes swap and ZFS ARC.
  • Disk usage - Host system. Supports multiple partitions and devices.
  • Disk I/O - Host system. Supports multiple partitions and devices.
  • Network usage - Host system and containers.
  • Load average - Host system.
  • Temperature - Host system sensors.
  • Fan speed - Host system sensors (Linux, via /sys/class/hwmon).
  • GPU usage / power draw - Nvidia, AMD, and Intel.
  • Battery charge - Host system and some peripherals.
  • Containers - Status and metrics of all running Docker / Podman containers.
  • S.M.A.R.T. - Host system disk health (includes eMMC wear/EOL and Linux mdraid array health via sysfs when available).
  • ZFS - Pool capacity, usage, health, I/O throughput, scrub status, and per-dataset usage.
  • Network monitors - ICMP, TCP, HTTP, and DNS response time and packet loss, probed from the agent. See Network Monitoring.
