RabbitMQ Trace的使用

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

可通过插件形式提供可视化界面

rabbitmq_tracing插件同样会对流入流出的消息做封装，然后将封装后的消息日志存入相应的trace文件之中

（1）安装rabbitmq_tracing 插件

　　选择开始菜单的RabbitMQ Command Prompt（sbin dir）

　   

　   进入C:\Program Files (x86)\RabbitMQ Server\rabbitmq_server-3.4.1\sbin输入命令

rabbitmq-plugins enable rabbitmq_tracing

 （2）浏览器打开http://localhost:15672，打开RabbitMQ的web监控工具

 （3）新增Trace

　　Virtual host为testhost，格式为Text，连接的 username（eg:admin），password（eg:admin）

　　在添加完trace之后，会根据匹配的规则将相应的消息日志输出到对应的trace文件之中

（4）测试

发送消息 bbbbbbbbbbbbbb

查看Trace拦截的信息

 （5）查看日志信息

直接点击“Trace log files”下面的列表直接查看对应的日志文件，如：testhost.log

说明：

　　需要自己手工生成日志文件后，收发消息才会有记录

注意：

　　打开 trace 会影响消息写入功能，适当打开后请关闭

关闭插件的命令

rabbitmq-plugins disable rabbitmq_tracing
