启动 docker-compose
使用下面的命令启动 docker-compose 定义的容器
查看 Prometheus 工作状态
打开 http://192.168.1.5:10221/targets 和 http://192.168.1.4:10442/targets
如果 State 都是 UP 即代表 Prometheus 工作正常，如下图所示：
配置 Grafana
打开 http://192.168.1.5:10220 使用默认账号密码 admin/admin 登录并修改密码后，默认进来是创建数据库的页面
创建数据源
创建图表
创建系统资源图表
创建docker资源图表
和上面一样,Import dashboard时id改成193就行
