对 Amazon A EC2 uto Scaling 中的问题进行故障排除

Amazon A EC2 uto Scaling 提供了具体的描述性错误来帮助您解决问题。可以从扩展活动的描述中发现错误消息。

检索来自扩缩活动的错误消息

要从扩展活动描述中检索错误消息,请使用describe-scaling-activities命令。您拥有可追溯到 6 周的扩展活动记录。扩展活动按开始时间排序,首先列出最新的扩展活动。

注意

扩展活动还会显示在 Amazon A EC2 uto Scaling 控制台的活动历史记录中,位于 Auto Scaling 组的 “活动” 选项卡上。

要查看特定 Auto Scaling 组的扩展活动,请使用以下命令。

aws autoscaling describe-scaling-activities --auto-scaling-group-name my-asg

在下面的示例响应中,StatusCode 包含活动的当前状态,StatusMessage 包含错误消息。

{ "Activities": [ { "ActivityId": "3b05dbf6-037c-b92f-133f-38275269dc0f", "AutoScalingGroupName": "my-asg", "Description": "Launching a new EC2 instance: i-003a5b3ffe1e9358e.

要查看已删除组的扩展活动

要在删除 Auto Scaling 组后查看伸缩活动,describe-scaling-activities请在命令中添加以下--include-deleted-groups选项。

aws autoscaling describe-scaling-activities --auto-scaling-group-name my-asg --include-deleted-groups

以下是示例响应,其中包含已删除组的扩展活动。
