Observability
Uptime Kuma
Self-hosted uptime monitor with its own notification history
What it does
Uptime Kuma monitors endpoint uptime and response time with a built-in dashboard and notification history, independent of any other monitoring stack.
How it runs here
Runs as a single-replica StatefulSet in the uptime-kuma namespace, keeping its monitor configuration and history on its own 1Gi Longhorn volume rather than an external database.
Connects to
Stands on its own.
Why I chose it
A second, independent uptime checker means a bug or outage in the primary monitoring stack does not also blind the status history.
