AWS CloudWatch 代理未启动

Question

我有一个 Ubuntu EC2 实例。我在以下位置手动创建了以下基本 CloudWatch 代理配置文件：

/opt/aws/amazon-cloudwatch-agent/etc/amazon-cloudwatch-agent.json

{
    "metrics": {
        "metrics_collected": {
            "collectd": {},
            "mem": {
                "measurement": [
                    "used_percent",
                    "total"
                ]
            },
            "disk": {
                "measurement": [
                    "used_percent",
                    "total"
                ]
            }
        }
    }
}

我正在尝试使用以下命令启动 CloudWatch 代理。

sudo /opt/aws/amazon-cloudwatch-agent/bin/amazon-cloudwatch-agent-ctl -m ec2 -a start

然后我使用下面的命令检查状态以确认它正在运行。

sudo /opt/aws/amazon-cloudwatch-agent/bin/amazon-cloudwatch-agent-ctl -m ec2 -a status

但是我得到下面的输出，显示代理处于停止状态。

{
  "status": "stopped",
  "starttime": "",
  "version": "1.223987.0"
}

我检查了下面的日志文件。

/var/log/amazon/amazon-cloudwatch-agent

它包含了：
