使用 EventBridge 和 CloudTrail 监控可中断容量预留

可中断容量预留会发送 EventBridge 通知和 CloudTrail 事件，以帮助您监控和响应容量更改。

EventBridge 通知

您会收到两种类型的 EventBridge 通知。有关如何设置 EventBridge 通知的信息，请参阅 Creating Amazon EventBridge rules。

实例中断警告

如果您在可中断预留中运行实例，则会在实例终止前 2 分钟收到此通知：

{
    "version": "0",
    "id": "12345678-1234-1234-1234-123456789012",
    "detail-type": "EC2 Interruptible Capacity Reservation Instance Interruption Warning",
    "source": "aws.ec2",
    "account": "[instance owner Account ID]",
    "time": "[Current time in yyyy-mm-ddThh:mm:ssZ]",
    "resources": "[instance arn]",
    "region": "[region]",
    "detail": {
        "instance-id": "[instance-id]",
        "instance-action": "terminate",
        "instance-termination-time": "yyyy-mm-ddThh:mm:ssZ",
        "azId": "[availability-zone-id]"
    }
}

回收完成

如果您拥有源预留，则在容量回收完成后会收到此通知：

{
    "version": "0",
    "id": "12345678-1234-1234-1234-123456789012",
    "detail-type": "EC2 Capacity Reservation Interruptible Reclamation Complete",
    "source": "aws.ec2",
    "account": "[source Capacity Reservation Owner Account ID]",
    "time": "[Current time in yyyy-mm-ddThh:mm:ssZ]",
    "region": "us-east-1",
    "resources": ["source_cr_arn"],
    "detail": {
        "sourceCapacityReservationId": "string",
        "instanceType": "string",
        "availabilityZoneId": "string",
        "TotalInstanceCount": "current total count in the source",
        "ReclaimedInstanceCount": "count of instances added to the source",
        "targetInstanceCount": "number"
    }
}

CloudTrail 事件

CloudTrail 会对可中断容量预留记录以下事件：

• InterruptibleCapacityReservationCreated：当您创建可中断分配时

• InterruptibleCapacityReservationAllocationUpdated：当您修改分配时

• InterruptibleCapacityReservationCancelled：当您取消分配时

• CapacityReservationModified：当我们修改源预留以进行分配时

• InterruptibleCapacityReservationInstancesTerminated：当我们在回收期间终止实例时
