AWS Cloudwatch日志窗口问题

Question

我正在尝试为我的Windows EC2实例设置cloudwatch日志，它是一台具有4.x版EC2Config的2008 r2服务器。

1.Instance已连接到它，具有完整的云监视访问权限。 2.为了安全起见，我也试过了Access键和Secret。

默认日志适用于cloudwatch我可以看到系统事件日志，但是当我从这里尝试json时https://cloudacademy.com/blog/centralized-log-management-with-aws-cloudwatch-part-2-of-3/

我看不到任何日志。这是json
