Modern status dashboard built with Next.js, featuring live checks, downtime alerts, and a clean UI.

npm install
npm run dev

Open http://localhost:3000.

npm run build
npm run start

• Admin Panel (no code required): Add, edit, enable/disable, and delete monitors and change all settings from a protected /admin UI — no code edits or redeploys. Changes are picked up by the monitoring loop live.
• Multiple monitor types: HTTP/HTTPS (status code + optional keyword match), TCP port, and ICMP ping.
• Live Monitoring: Background checks with configurable intervals and timeouts.
• Modern UI: Clean dashboard built with Next.js App Router and Tailwind CSS.
• Timeline View: Visual history of site health and latency.
• Configurable branding: Site name, tagline, and footer editable from the admin UI.
• Notifications: Email, Google Chat, MS Teams, and Telegram — editable from the admin UI (DB-backed, with env fallback).
• Data retention: Old check history is auto-pruned on a configurable schedule.

Everything is now managed at runtime — lib/config.ts only seeds the initial monitors on first run.

1. Set an admin password and session secret (see Environment Variables).
2. Visit /admin — you'll be redirected to the login page.
3. Log in with ADMIN_PASSWORD. From there you can:
   • Monitors: add/edit/delete HTTP, TCP, or Ping monitors; toggle enabled; set interval/timeout.
   • Settings: branding (name/tagline/footer/meta), notification channels, data retention, and change the admin password.

Monitors and settings are stored in the SQLite database (persisted via the Docker volume), so they survive restarts. Deleting a monitor keeps its historical uptime data.

ICMP Ping monitors require the NET_RAW capability in Docker (already set in docker-compose.yaml) and the iputils package (installed in the Dockerfile).

Copy sample.env to .env and adjust:

# Admin panel (required for /admin)
ADMIN_PASSWORD=changeme
SESSION_SECRET=a-long-random-stable-string

# Notifications (initial defaults — also editable from the admin UI)
EMAIL_ENABLED=true
EMAIL_HOST=smtp.example.com
EMAIL_USER=user@example.com
EMAIL_PASS=password
EMAIL_TO=admin@example.com
GOOGLE_CHAT_WEBHOOK_URL=https://chat.googleapis.com/...
TEAMS_WEBHOOK_URL=https://outlook.office.com/...

# Telegram — bot token from @BotFather, chat ID from @userinfobot
TELEGRAM_ENABLED=true
TELEGRAM_BOT_TOKEN=123456:ABC-DEF...
TELEGRAM_CHAT_ID=123456789

SESSION_SECRET must be a long random string and stable across restarts (otherwise active admin sessions are invalidated). The notification env vars are used as field-level fallbacks until you save notification settings in the admin UI.

• app/: Routes, layouts, and metadata.
• features/: Domain logic (status monitoring, notifications).
• components/ui/: Reusable UI components.
• lib/: Cross-feature utilities (database, config, env validation).
