# Amazon ECS 容器实例运行状况更改事件
<a name="ecs_container_instance_health_events"></a>

以下方案将引起容器实例运行状况更改事件。

**Amazon ECS 容器代理检测容器运行时运行状况的变化。**

容器代理会定期评估容器实例上容器运行时（例如 Docker 进程守护程序）的运行状况。如果运行时无响应或恢复，代理会报告该变化并生成事件。

可用性：EC2 启动类型。

**Amazon ECS 容器代理检测加速计算设备运行状况的变化。**

对于具有加速计算设备（如 GPU）的实例，容器代理会监控设备运行状况。如果设备受损或恢复，则会生成事件。

可用性：Amazon ECS 托管实例启动类型。

**Amazon ECS 容器代理检测进程守护程序运行状况的变化。**

容器代理监控容器实例上所需的进程守护程序任务。如果进程守护程序任务失败，则系统会生成事件。

可用性：Amazon ECS 托管实例启动类型。

**容器实例的整体运行状况发生变化。**

Amazon ECS 根据各项运行状况检查结果计算整体运行状况。当整体状态转换时，系统会生成事件。

可用性：Amazon ECS 托管实例和 EC2 启动类型。
