Stats in management UI are disabled on this node

今天使用docker安装了个rabbitmq，访问UI界面的【Channels菜单】有这样的提示：

Stats in management UI are disabled on this node

原因：

The reason is that the default image disables metrics collector in the management_agent plugin:

# cat /etc/rabbitmq/conf.d/management_agent.disable_metrics_collector.conf 
management_agent.disable_metrics_collector = true

 For deployment, you could turn it on or off through the configuration file. The instruction could be found ：
