- Enable Prometheus metrics endpoint in n8n, InfluxDB, and Home Assistant.
- Add ServiceMonitor configs for scraping metrics, including token authentication for Home Assistant.
- Define native PrometheusRules for health checks, restarts, volume capacities, and n8n event loop lag to prevent login freezes.
- Deploy AlertmanagerConfigs to route alerts from the new namespaces to Telegram.
