Amazon web services Ubuntu 16.04上的awslogs服务和CloudWatch日志代理出现问题

在运行Ubuntu 16.04的一个AWS ec2实例上，我的/var/syslog中填写了以下错误

/var/log/awslogs.log包含以下消息：

任何有关此问题的疑难解答都会有很大帮助。

以下链接中发布了类似问题-

我做了以下工作：

a） 停止了awslogs服务

$ service awslogs stop

$ service awslogs start

b） 删除了/var/awslogs/state/中的代理状态文件/（我在本例中重命名了它）

c） 重新启动了awslogs服务

$ service awslogs stop

$ service awslogs start

---

因此创建了一个新的代理状态文件，在此之后我的帖子中提到的错误消失了。

请根据您的Linux版本尝试以下命令

sudo服务awslogs启动

如果您正在运行AmazonLinux2，请尝试以下命令 sudo系统控制启动awslogsd

我花了2个小时才弄明白这一点

请查看实际的代理日志文件，

/var/log/awslogs.log

，了解有关问题的详细信息。编辑此帖子以添加/var/log/awslogs.log中的代码段
