Inside an LXC guest, lxcfs serves /proc/stat with the counters of the host cores in the guest's cpuset, so an idle guest sharing a core with a busy neighbor reported near-100% CPU. When the agent detects it is running in an LXC guest (lxcfs mounted on /proc/stat, container=lxc, or /run/systemd/container), derive CPU usage from the guest's own cgroup instead: cpu.stat on cgroup v2, cpuacct on v1, read at the cgroup mount root so it covers every process in the guest. Usage is normalized by the usable cores (the smallest of the affinity mask, cpuset and CPU quota). Per-core usage is omitted in this mode, since the per-core /proc/stat counters describe shared host cores and would contradict the total. Iowait and steal are not available from cgroup accounting and report as zero. Hosts and Docker/Podman agents are unaffected and keep reading /proc/stat, as does an LXC guest whose cgroup accounting is unreadable. --------- Co-authored-by: hank <hank@henrygd.me>
Beszel
Beszel is a lightweight server monitoring platform that includes Docker statistics, historical data, and alert functions.
It has a friendly web interface, simple configuration, and is ready to use out of the box. It supports automatic backup, multi-user, OAuth authentication, and API access.
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.
Getting started
The quick start guide and other documentation is available on our website, beszel.dev. You'll be up and running in a few minutes.

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.
