[英]AWS CloudWatch Alarms to multiple EC2 instances

I'm wanting to apply a CloudWatch alarm to stop instances which aren't being used in our pre-production environment. 我想应用CloudWatch警报来停止未在我们的预生产环境中使用的实例。 We often have instances being spun up, used and then left turned on which is really starting to cost us a fair amount of money. 我们经常会出现旋转，使用然后再打开的情况，这真的开始花费我们相当多的钱。

CloudWatch alarms have a handy feature whereby we can stop based on some metrics - this is awesome and what I'd like to use to constantly keep an eye on the servers with but let it tidy up the instances for me. CloudWatch警报有一个方便的功能，我们可以根据一些指标停止 - 这是非常棒的，我想用它来不断关注服务器，但让它为我整理实例。

The problem with this is that it appears that the CloudWatch alarms need to be created individually against each instance. 这样做的问题是，似乎需要针对每个实例单独创建CloudWatch警报。 Is there a way in which I can create one alarm which would share values across all current and future instances which will be started? 有没有办法可以创建一个警报，它将在所有当前和未来的实例中共享值？

ETA - Alternatively, tell me that these options are better than CloudWatch and I'll be happy at that. ETA - 或者，告诉我这些选项比CloudWatch更好，我会很高兴。

Add a startup script that creates the CloudWatch alarm to the base image you use to generate your VMs. 将创建CloudWatch警报的启动脚本添加到用于生成VM的基本映像。

I don't believe this is possible - CloudWatch seems designed to be 'very manual' or 'very automated'. 我不相信这是可能的 - CloudWatch似乎设计为“非常手动”或“非常自动化”。 ie You can't setup one alarm which would go off if any one instance is idle, you have to setup individual alarms for each instance. 即，如果任何一个实例处于空闲状态，您无法设置一个警报，您必须为每个实例设置单独的警报。

A couple of possible solutions, which are probably not what you want to hear: 一些可能的解决方案，可能不是您想听到的：

Script your instance creation, and add a call to cloudwatch to create an alarm for each instance. 编写实例创建脚本，并添加对cloudwatch的调用以为每个实例创建警报。
Run a service continually, which looks for instances and checks to ensure that there is an alarm for the instance, create alarms for the new instances, and remove alarms for instances which have been terminated. 持续运行服务，查找实例并检查以确保实例有警报，为新实例创建警报，并删除已终止实例的警报。
