Amazon A EC2 uto Scaling 事件参考

使用 Amazon EventBridge，您可以创建匹配传入事件的规则，并将它们路由到目标进行处理。

生命周期操作事件

当您向 Auto Scaling 组添加生命周期挂钩 EventBridge时，Amazon A EC2 uto Scaling 会在实例过渡到等待状态时向发送事件。事件会尽可能生成。

横向扩展生命周期操作

以下示例事件显示，由于启动生命周期挂钩，Amazon A EC2 uto Scaling 将实例移至Pending:Wait状态。

{
  "version": "0",
  "id": "12345678-1234-1234-1234-123456789012",
  "detail-type": "EC2 Instance-launch Lifecycle Action",
  "source": "aws.autoscaling",
  "account": "123456789012",
  "time": "yyyy-mm-ddThh:mm:ssZ",
  "region": "us-west-2",
  "resources": [
    "auto-scaling-group-arn"
  ],
  "detail": { 
    "LifecycleActionToken": "87654321-4321-4321-4321-210987654321", 
    "AutoScalingGroupName": "my-asg", 
    "LifecycleHookName": "my-lifecycle-hook", 
    "EC2InstanceId": "i-1234567890abcdef0", 
    "LifecycleTransition": "autoscaling:EC2_INSTANCE_LAUNCHING",
    "NotificationMetadata": "additional-info",
    "Origin": "EC2",
    "Destination": "AutoScalingGroup"
  } 
}

横向缩减生命周期操作

以下示例事件显示，由于终止生命周期挂钩，Amazon A EC2 uto Scaling 将实例移至Terminating:Wait状态。

重要

当自动扩缩组在横向缩减时将实例退回暖池的情况下，将实例退回暖池也会生成 EC2 Instance-terminate Lifecycle Action 事件。当实例在横向缩减时移至等待状态的情况下，所传递的事件都将 WarmPool 作为 Destination 的值。有关更多信息，请参阅 Instance reuse policy。

{
  "version": "0",
  "id": "12345678-1234-1234-1234-123456789012",

    "Destination": "EC2"
  } 
}

扩缩成功的事件

以下示例演示扩缩成功的事件的事件类型。事件会尽可能生成。

横向扩展成功的事件

以下示例事件显示 Amazon A EC2 uto Scaling 成功启动了一个实例。

    "Origin": "EC2",
    "Destination": "AutoScalingGroup"
  }
}

横向缩减成功的事件

以下示例事件显示 Amazon A EC2 uto Scaling 成功终止了一个实例。

重要

当自动扩缩组在横向缩减时将实例退回暖池的情况下，将实例退回暖池也会生成 EC2 Instance Terminate Successful 事件。实例成功退回暖池时传送的事件都将 WarmPool 作为 Destination 的值。有关更多信息，请参阅 Instance reuse policy。
