# 预配置的警报
<a name="hyperpod-observability-addon-alerts"></a>

Amazon SageMaker HyperPod (SageMaker HyperPod) 可观察性插件启用集群和工作负载的默认警报，以便在系统检测到集群性能不佳的常见早期指标时通知您。这些警报是在 Amazon Managed Grafana 内置警报系统中定义的。有关如何修改这些预配置的警报或创建新警报的信息，请参阅《Amazon Managed Grafana 用户指南》**中的 [Grafana 版本 10 中的警报](https://docs.aws.amazon.com/grafana/latest/userguide/v10-alerts.html)。以下 YAML 显示了默认警报。
