ℹ️ About This Monitor
A real-time website monitoring dashboard that tracks the availability, response time, and uptime of multiple websites across different business groups. When a site goes down, email alerts are automatically sent to the designated group contact.
🛠️ Tech Stack

⚙️ How It Works
- 🔍 Health Check: Each check sends HTTP GET to every enabled site. Status code, latency, and errors are recorded.
- 💾 D1 Logging: Every result is stored in
status_log. Records older than 30 days are automatically purged. - 🔔 Alert Routing: If a site is down and no alert was sent in the past hour, an email goes to the group's designated contact.
- 🛡️ Admin Panel: Add, edit, or remove monitored sites through the admin panel (password protected).
- 🌐 WAF Integration: Cloudflare zones are configured to allow monitoring traffic through challenge pages.
- ⏱️ Auto-Refresh: Dashboard checks every 5 minutes when the page is open.
