rabbitmq消息追踪
一旦开启，会影响性能，除非需要分析的时候才开启，否则不开启
一、firehose：不常用
二、rabbitmq_tracing：较常用
可通过管理界面查看分析，其实底层就是firehose，只不过可以用界面查看更方便
1、开启rabbitmq_tracing
进入rabbitmq的sbin文件夹。我的目录为D:\Program Files\RabbitMQ Server\rabbitmq_server-3.8.5\sbin，打开cmd窗口，执行如下命令。然后重启mq
rabbitmq-plugins enable rabbitmq_tracing
2、浏览器打开http://localhost:15672，点击Admin
界面会增加一个Tracing按钮
3、添加一个trace
1、format：一般选择text模式方便人去查看；json模式进行base64编码，是方便以后导出用来做程序分析的
2、max那个不用写
3、pattern：用#，表示无论是发起方发送消息还是接收方接收消息，都做记录；用publish.#，表示只记录发起方发送记录；用deliver.#，表示只记录接收方处理记录
添加后如下图：
4、查看log文件
直接点击“Trace log files”下面的列表查看对应的日志文件，如：test.log

5、关闭rabbitmq_tracing：记住，查看完后要关闭，否则影响消息写入性能
进入rabbitmq的sbin文件夹。我的目录为D:\Program Files\RabbitMQ Server\rabbitmq_server-3.8.5\sbin，打开cmd窗口，执行如下命令。然后重启mq
rabbitmq-plugins disable rabbitmq_tracing
