# Monitoring & API Testing

* **Single Request Test**: Use Postman or similar tools to test your vLLM container endpoint.
* **Autoscaling Test**: Use Locust to simulate load and validate replica scaling.
* **Usage Metrics**: Monitor replica count, request rate, and system response time.
* **Runtime Logs**:
  * Logs are displayed per container instance and replica.
  * You can access real-time and historical logs from the Air Cloud dashboard.
  * Logs are shown in reverse chronological order.
  * Use filters to view logs by time range, container, or instance ID.
  * Logs include startup command output, health check status, error messages, and stdout/stderr of model servers.
  * If your container fails, logs will be preserved for a limited retention window for debugging.
* **Settings**: You can update endpoint settings only when the container is stopped.
