Monitoring a static site is simpler than a dynamic one — no database, no PHP, no queues. Just check three things: the home page returns 200, the SSL certificate is valid, and the VPS disk isn't full. GitHub CMS includes a built-in health-check script that runs every 5 minutes via cron and sends Telegram alerts on failures.

FAQ
How often should I check a static site?
Every 5 minutes via cron — sufficient for static sites. Each check takes < 1 second and creates no load.
What if health-check shows an error?
1. Check nginx: systemctl status nginx. 2. Check disk: df -h. 3. Check SSL: certbot certificates. 4. If OK — check DNS. GitHub CMS with symlink deployment allows rollback in 0.1s.
