Trace 是Rabbitmq用于记录每一次发送的消息，方便使用Rabbitmq的开发者调试、排错。

1、启动Tracing插件

在RabbitMQ中默认是关闭的，需手动开启。此处rabbitMQ是使用docker部署的

## 进入rabbitMq中
docker exec -it rabbitmq1 bash
## 启动日志插件
rabbitmq-plugins enable rabbitmq_tracing
## 开启rabbitmq的tracing插件
rabbitmqctl trace_on

开启了插件后，无需重启，rabbitMq管理界面就会出现Tracing项，可新建追踪。
