+### Automatic Monitoring and Metrics Collection
+
+**Metrics collector runs automatically** on container startup and is monitored by cron every 3 minutes. If the process crashes, it will be automatically restarted.
+
+Check metrics collector logs:
+```bash
+docker compose exec web tail -f /var/log/metrics_collector.log
+```
+
+Check monitoring script logs:
+```bash
+docker compose exec web tail -f /var/log/metrics_monitor.log
+```
+
+Restart metrics collector manually:
+```bash
+docker compose exec web pkill -f collect_metrics.php
+# It will be auto-restarted within 3 minutes by the monitoring script
+```
+
 ### Automatic Client Expiration Check
 
 **Runs automatically in Docker container** every hour to disable expired clients.
