# Amazon ECS 容器執行個體運作狀態變更事件
<a name="ecs_container_instance_health_events"></a>

下列案例會導致容器執行個體運作狀態變更事件。

**Amazon ECS 容器代理程式會偵測容器執行時間運作狀態的變更。**

容器代理程式會定期評估容器執行個體上容器執行時間 （例如 Docker 協助程式） 的運作狀態。如果執行時間變得沒有回應或復原，代理程式會報告變更並產生事件。

可用性：EC2 啟動類型。

**Amazon ECS 容器代理程式會偵測加速運算裝置運作狀態的變更。**

在具有 GPUs 等加速運算裝置的執行個體上，容器代理程式會監控裝置運作狀態。如果裝置受損或復原，就會產生事件。

可用性：Amazon ECS 受管執行個體啟動類型。

**Amazon ECS 容器代理程式會偵測協助程式運作狀態的變更。**

容器代理程式會監控容器執行個體上所需的協助程式任務。如果協助程式任務失敗，會產生事件。

可用性：Amazon ECS 受管執行個體啟動類型。

**容器執行個體的整體運作狀態會變更。**

Amazon ECS 會從個別運作狀態檢查結果計算整體運作狀態。當整體狀態轉換時，會產生事件。

可用性：Amazon ECS 受管執行個體和 EC2 啟動類型。

## 範例容器執行個體運作狀態變更事件
