尽管角色和策略正确，但适用于EC2的CloudWatch Logs Unified Agent无法创建日志组

Question

我遵循了此页面上有关查看[CloudWatch中的Apache日志]（https://aws.amazon.com/blogs/mt/simplifying-apache-server-logs-with-amazon-cloudwatch-logs-insights/）的说明

Apache工作正常。 access和error日志都在我在apache配置文件中指定的文件夹上生成。我已按照指定配置了代理文件，当我尝试重新启动代理时，该文件运行无任何错误。我什至将"namespace": "CWAgent"添加到配置中。

但是，我在CloudWatch中没有看到任何日志组。我对安装了日志代理的EC2实例所附加的角色授予了正确的策略权限。它似乎仍然没有解决。

                }
        }
}

即使在代理日志文件中，我也看不到任何错误消息。它在那里发送完整尺寸。
