# 預先設定的警示
<a name="hyperpod-observability-addon-alerts"></a>

Amazon SageMaker HyperPod (SageMaker HyperPod) 可觀測性附加元件可為您的叢集和工作負載啟用預設警示，以在系統偵測到叢集效能不佳的常見早期指標時通知您。這些警示是在 Amazon Managed Grafana 內建警示系統中定義。如需如何修改這些預先設定警示或建立新警示的相關資訊，請參閱《Amazon Managed Grafana 使用者指南》**中的 [Grafana 第 10 版中的警示](https://docs.aws.amazon.com/grafana/latest/userguide/v10-alerts.html)。下列 YAML 會顯示預設警示。
