Previously, the uptime status endpoint returned HTTP 400 with
“未配置 Uptime Kuma URL/Slug” when either option was not set, resulting in
frontend error states.
Changes:
• Treat absence of `UptimeKumaUrl` or `UptimeKumaSlug` as a valid scenario.
• Immediately respond with HTTP 200, `success: true`, and an empty `data` array.
• Preserve existing behavior when both options are provided.
This prevents unnecessary error notifications on the dashboard when
Uptime Kuma integration is not configured and improves overall UX.
Introduce application uptime monitoring to improve observability and reliability.
• Add UptimeService to track process start time and expose uptime in seconds
• Create /health/uptime endpoint returning the current uptime in JSON format
• Integrate uptime metric into existing health-check middleware
• Update README with instructions for consuming the new endpoint
• Add unit tests covering UptimeService and new health route
This change enables operations teams and dashboards to programmatically
determine how long the service has been running, facilitating automated
alerts and trend analysis.
