CloudWatch 代理在 AWS EC2 实例上启动后不久就会在传递 Elastic Beanstalk 日志文件时停止

Question

我的 AWS EC2 实例上的 AWS CloudWatch Agent 服务遇到问题。配置 CloudWatch 代理以从 Elastic Beanstalk 收集日志并启动服务后，该服务在启动后不久停止。我已验证 CloudWatch Agent 包已安装，并且 JSON 配置文件的格式似乎正确。

我已按照 AWS 文档进行操作并配置了 CloudWatch Agent JSON 文件 (

amazon-cloudwatch-agent.json

)，如下所示：

{
  "agent": {
    "metrics_collection_interval": 60,
    "run_as_user": "root"
  },
  "logs": {
    "logs_collected": {
      "files": {
        "collect_list": [
          {
            "file_path": "/var/log/nginx/access.log",
            "log_group_name": "MyApp-Backend-Logs",
            "log_stream_name": "Development-Stream",
            "timezone": "UTC"
          }
        ]
      }
    }
  }
}

尽管进行了这些配置，CloudWatch Agent 服务在启动后不久就会停止，我不确定是什么导致了此行为。

预期行为： CloudWatch Agent 服务应成功启动并继续运行，从指定的 Elastic Beanstalk 环境收集日志并将其发送到 CloudWatch Logs。

实际行为： CloudWatch Agent 服务在启动后不久就会停止，并且不会收集日志或将日志发送到 CloudWatch Logs。

以下是我观察到的其他日志消息：

也遇到这个问题。几个月前就开始了。 Cloudtrail 和日志中没有错误。
