-- Logs rotate automatically
-- Real-time monitoring available

+Coordinator observability endpoints:
+ - JSON metrics endpoint: `http://localhost:8000/v1/metrics`
+ - Prometheus metrics endpoint: `http://localhost:8000/metrics`
+ - Health endpoint: `http://localhost:8000/v1/health`
+ - Web dashboard source: `/opt/aitbc/website/dashboards/metrics.html`
+
+Current monitoring flow:
+ - FastAPI request middleware records request counts, error counts, response time, and cache stats
+ - `metrics.py` calculates live metric summaries and alert thresholds
+ - `/v1/metrics` returns JSON for dashboard consumption
+ - `/metrics` remains available for Prometheus-style scraping
+ - Alert delivery uses webhook dispatch when `AITBC_ALERT_WEBHOOK_URL` is configured, otherwise alerts are logged locally
