AWS Cloudwatch 日志状态显示 运行 但日志在 AWS 控制台中不可用

Question

我是aws新手，需要将应用服务日志发布到cloud watch。我尝试了 AWS 文档中提到的步骤及其工作。我通过 jenkins 管道配置了相同的步骤。在这里，我面临一个问题。日志未发布，即我无法从 AWS 控制台看到日志。我登录到 ec2 实例并检查 cloudwatch 服务状态，它显示

{
  "status": "running",
  "starttime": "2021-03-25T07:40:21+0000",
  "configstatus": "configured",
  "cwoc_status": "stopped",
  "cwoc_starttime": "",
  "cwoc_configstatus": "not configured",
  "version": "1.247347.3b250378"
}

不明白这里有什么问题:(。

任何帮助都会有所帮助。

提前致谢。

我关注了你提到的link Installing and Running the CloudWatch Agent on Your Servers。

下面是我用于推送日志和一些其他指标的配置，由这个命令生成

Run the CloudWatch Agent Configuration Wizard

sudo /opt/aws/amazon-cloudwatch-agent/bin/amazon-cloudwatch-agent-config-wizard

{
        "agent": {
                "metrics_collection_interval": 60,
                "run_as_user": "root"
        },
        "logs": {
                "logs_collected": {
                        "files": {
                                "collect_list": [
                                        {
                                                "file_path": "/var/log/messages",
                                                "log_group_name": "messages",
                                                "log_stream_name": "{instance_id}"
                                        }
                                ]
                        }
                }
        },
        "metrics": {
... # metrics configuration here
        }
}

按照文档中的描述启动客户端

/opt/aws/amazon-cloudwatch-agent/bin/amazon-cloudwatch-agent-ctl -a \
fetch-config -m ec2 -s -c file:///opt/aws/amazon-cloudwatch-agent/bin/config.json

Start the CloudWatch Agent Using the Command Line

# /opt/aws/amazon-cloudwatch-agent/bin/amazon-cloudwatch-agent-ctl -a status
{
  "status": "running",
  "starttime": "2021-03-26T11:46:14+0000",
  "version": "1.247345.35"
}

有问题可以到logs目录里面找

[root@ip-xx amazon-cloudwatch-agent]# ls
amazon-cloudwatch-agent.log  configuration-validation.log  state
[root@ip-xx amazon-cloudwatch-agent]# pwd
/var/log/amazon/amazon-cloudwatch-agent

附带说明一下，如果我只想将日志推送到 cloudwatch，我会使用这个
