# Amazon Elastic Compute Cloud (EC2) 執行個體
<a name="component-configuration-examples-ec2"></a>

下列範例顯示 Amazon EC2 執行個體 JSON 格式的元件組態。

**重要**  
當 Amazon EC2 執行個體進入 `stopped` 狀態時，系統便會將其從監控中移除。當其回到 `running` 狀態時，便會新增到在 CloudWatch Application Insights 主控台 **Application details** (應用程式詳細資訊) 頁面上的 **Unmonitored components** (未受監控的元件) 清單。如果為應用程序啟用對新資源的自動監控，則會將執行個體新增到 **Monitored components** (受監控的元件)。但是，系統會將工作負載的日誌和指標設為預設值。不會儲存先前的日誌和指標組態。
