我想在我的生产服务器上设置 cloudwatch 警报，但在解决它时收到 libwww-perl 的依赖项错误，尽管有空间，但说"设备上没有空间"。 请让我知道我缺少什么。

您的索引节点使用率很高。这基本上意味着您的服务器上有很多小文件(因为磁盘仍然没有满(。
因此，您需要找到这些小文件并删除旧的/不需要的文件。
同时，作为一种快速解决方法，您可以尝试自动删除不需要的软件包。
sudo apt-get autoremove
或
sudo apt autoremove
注意：这不是永久解决方案。这只是一个快速解决方案。
您一定会一次又一次地面临此问题，除非您找到这些小文件的创建位置并编写cron job以定期删除它们。
