提前感谢您的帮助。我是AWS的新手。
我尝试将NGINX日志从我的EC2示例记录到CloudWatch，但我无法使其工作，我不知道我错过了什么。
总结一下，我遵循的步骤是：
1.当我在docker中运行NGINX时，我将卷Map到我的本地文件夹（假设为/home/ubuntu/nginx/logs/），并检查它是否登录到文件access.logerror.logjson_access.log
1.我安装了CloudWatch代理如下：https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/download-cloudwatch-agent-commandline.html
1.我使用CloudWatchAgentServerPolicy策略创建了一个IAM角色。
1.我将该IAM角色添加到运行NGINX的EC2示例中
1.我使用sudo /opt/aws/amazon-cloudwatch-agent/bin/amazon-cloudwatch-agent-config-wizard配置了CloudWatch代理，并给出了以下答案：
1.您计划在哪个操作系统上使用代理？答：Linux
1.您使用的是EC2主机还是本地主机？EC2
1.您计划由哪个用户运行代理？答：根
1.是否要打开StatsD守护程序？答：否
1.是否要监视CollectD中的指标？答：否
1.是否要监视任何主机指标？答：否
1.您是否有任何现有的CloudWatch日志代理？答：否
1.是否要监视任何日志文件？答：是的
1.日志文件路径：/home/Ubuntu/nginx/logs/
1.日志组名称：nginx
1.日志流名称：[{instance_id}]（默认）
1.是否要指定要监视的任何其他日志文件？答：否
1.是否要将配置存储在SSM参数存储区中？答：否
1.我启动了代理：sudo /opt/aws/amazon-cloudwatch-agent/bin/amazon-cloudwatch-agent-ctl -a start
通过这些步骤，我希望代理会自动推送日志组并流到cloudwatch中，并且我会在CloudWatch〉Log groups〉nginx〉myinstanceid中获得所有原始日志。
但这并没有发生。
因此，我手动创建了日志组和日志流，命名方式与配置中的相同，但仍然没有任何结果。我还尝试使用显式日志流名称重做所有内容，以防我拼写错误的示例ID，但没有任何结果。
这是向导生成的config.json：

{
    "agent": {
        "run_as_user": "root"
    },
    "logs": {
        "logs_collected": {
            "files": {
                "collect_list": [
                    {
                        "file_path": "/home/ubuntu/nginx/logs/",
                        "log_group_name": "nginx",
                        "log_stream_name": "{instance_id}",
                        "retention_in_days": 30
                    }
                ]
            }
        }
    }

我错过了什么？或者我做错了什么？
再次感谢你！
