Who monitors your Uptime Kuma? Three ways to watch the watcher

Описание и применение

Установка второго экземпляра Uptime Kuma, настройка «dead‑man’s switch» и внешней проверки статуса обеспечивают надёжное оповещение при сбоях хоста.

Задача

Uptime Kuma runs on your own host, so if that host, its power, or your home uplink fails, Kuma stops monitoring and alerts.

Результат

Implementing a second monitor, a dead‑man’s switch, and an external HTTP check provides comprehensive coverage against host or network failures for Uptime Kuma.

Рабочий процесс

• 1. Deploy a second Uptime Kuma instance on a separate device or VPS and configure each to monitor the other.
• 2. Set up a dead‑man’s switch by having the Kuma host call a heartbeat URL every few minutes via cron; when calls stop, an external service alerts you.
• 3. Configure an external uptime monitor to perform an HTTP check of the Kuma status page to catch DNS or reverse‑proxy failures.

Доказательства

Uptime Kuma is the default self‑hosted monitor for good reason: 20-second checks, 90+ notification services and status pages, all in one container.
