Nezha Monitoring

Simply put, it is a "watchdog" installed on your own server. It monitors your server status (CPU, RAM), checks if websites are reachable, and tracks SSL certificate expiration, even executing scheduled tasks for you.

Solves the anxiety of "not knowing the server is down" or "website inaccessible due to expired certs". Compared to paid monitoring, it is free and data stays yours; compared to manual checks, it alerts you automatically.
