# Beszel (Domain-Enhanced Fork)

> **A fork of [Beszel](https://github.com/henrygd/beszel)** with added domain and SSL certificate monitoring capabilities.

Beszel is a lightweight server monitoring platform that includes Docker statistics, historical data, and alert functions. **This fork extends Beszel with domain and SSL certificate monitoring**, combining the best of server metrics with domain expiration tracking in a single dashboard.

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

### Server Monitoring (from Beszel)
- **Lightweight**: Smaller and less resource-intensive than leading solutions.
- **Simple**: Easy setup with little manual configuration required.
- **Docker stats**: Tracks CPU, memory, and network usage history for each container.
- **System metrics**: CPU, memory, disk usage, disk I/O, network, load average, temperature, GPU usage, battery status.
- **S.M.A.R.T. monitoring**: Disk health tracking including eMMC wear/EOL and Linux mdraid array health.
- **Alerts**: Configurable alerts for CPU, memory, disk, bandwidth, temperature, load average, and status.

### Domain & SSL Monitoring (added)
- **Domain expiration tracking**: Monitor domain expiration dates across multiple registrars.
- **SSL certificate monitoring**: Track SSL certificate validity and expiration dates.
- **Expiration alerts**: Get notified before domains or certificates expire.
- **Registrar integration**: Support for multiple domain registrars.

### Platform Features
- **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.
<!-- - **REST API**: Use or update your data in your own scripts and applications. -->

## Architecture

Beszel consists of two main components: the **hub** and the **agent**. This fork adds a **domain monitor** component.

- **Hub**: A web application built on [PocketBase](https://pocketbase.io/) that provides a dashboard for viewing and managing connected systems and domains.
- **Agent**: Runs on each system you want to monitor and communicates system metrics to the hub.
- **Domain Monitor**: Tracks domain and SSL certificate expiration data from configured registrars.

## Getting started

The [quick start guide](https://beszel.dev/guide/getting-started) and other documentation is available on the original Beszel website, [beszel.dev](https://beszel.dev). You'll be up and running in a few minutes.

### Domain Monitoring Setup

1. Go to Settings > Domain Monitor in the dashboard
2. Add your domain registrar API credentials
3. Configure domains to monitor
4. Set alert thresholds for expiration warnings
