我对 AWS 和 EC2 实例非常陌生。我的 EC2 实例每隔一两天就会失败，我不知道为什么。它说 1/2 状态检查失败。我尝试修复任何错误（我不相信有）我也更改了 ec2 实例。我创建了一个全新的实例，但仍然有同样的问题。我可以重新启动，但第二天就会失败。如果有人能帮忙，我将不胜感激！！！
编辑：为了提供更多背景信息，我在 EC2 实例上运行了一些 Docker 容器。Docker 容器来自 The Things Network (https://www.thethingsindustries.com/docs/getting-started/installation/）我严格按照说明进行操作，并确保安装后没有出现任何错误。

答案1
我会监控您的 EC2 实例的几种资源。
默认情况下，您只能看到 CPU。如果您安装CloudWatch 代理，您可以收集诸如 RAM 或磁盘之类的额外指标，这些指标是虚拟机管理程序无法直接猜测的。
然后，您可以查看实例失败时的指标，以检查是否存在一些意外的资源消耗。
我过去遇到过一些问题，由于缺少可用 RAM 而导致了与您描述类似的行为。
