RabbitMq（十七）rabbitmq的四种集群监控
rabbitmq的四种集群监控方式：
- rabbitmq控制台页面监控
- tracing日志监控
- 使用api接口自定义实现监控
- 使用Zabbix监控rabbitmq
第一种、使用控制台页面监控rabbitmq
网址：http://mq服务ip:15672 登录，可以根据不同菜单中对各项信息进行查看。
第二种、通过tracing日志查看消息的发送流程
参阅文章：消息的追踪查看配置及查看方法 ，通过log文件信息查看消息的发送、接收时间。
第三种、通过restful api接口自定义监控实现
登录控制台地址后，访问地址 http://172.18.255.118:15672/api/index.html ，ip为服务器地址，可以看到api文档相关介绍。通过api接口我们可以实现自己的监控内容以及界面。
eg：登录后请求地址 http://172.18.255.118:15672/api/connections 返回信息如下：

第四种、通过Zabbix监控rabbitmq（内容过多，这里不做介绍）
