AWS:为什么我的弹性豆柄应用会周期性地陷入严重的健康状态？

Question

我有一些使用默认设置运行的EB实例，但是即使它们目前几乎什么都不做(实际上只是运行静态的保持页面，没有访问者)，但它们仍然陷入严重的健康问题的时刻。

为什么会这样呢？我应该担心吗？同样，它们使用默认的EB设置进行配置。

更新

这是访问日志。他们支持@bazze的假设，即EB健康检查将几个常见的uRLs作为测试，而404作为回复：

Answer 1

您可以在事件的详细信息中看到原因。它说，100%的请求与4XX状态代码失败。所以我的猜测是，根据你问题中的信息，这些网站基本上是闲置的，而不是被使用的，你只是不时地从一个机器人那里得到一个访问，寻找共同的目录和文件来找到一些要黑客的东西。检查访问日志，您可以快速确认是否是这种情况。

更新:当为EB环境启用了增强的健康报告，并且没有操作正在进行时，HTTP请求是环境健康的主要来源。在文档中读到更多关于它的信息。
