Based on zipkin, a distributed tracking analysis application is built, which can be used to view the invocation process, time-consuming and service dependencies between service chains.
Especially in the late analysis of performance can be used as a reference basis, according to individual needs to choose to use.
Introduction:
Twitter's zipkin is a distributed tracking system dedicated to collecting time data for all Twitter distributed services. It provides two services: data collection and data query. The theoretical model of the system comes from the paper of Google Dapper. By collecting tracking data, developers can gain insight into how to execute a particular request in a distributed system.

rabbitMQ
I downloaded the docker image directly from Aliyun.
docker pull registry.cn-hangzhou.aliyuncs.com/zp-k8s/rabbitmq:3-management
docker run -d --net host --name rabbitmq registry.cn-hangzhou.aliyuncs.com/zp-k8s/rabbitmq:3-management
Docker exec-it container id/bin/bash
Find rabbit installation directory through find command
Find rabbitmqctl execution
./rabbitmqctl add_user admin 111111
./rabbitmqctl set_user_tags admin administrator
After configuring user passwords and permissions, log in to webUI
So far, all the configurations of the zipkin-server end have been completed.

So far, start zipkin-server, service 1, service 2
Visit http://localhost:9981/order-info-cycle/1
Return: {order=1 order information.... coupon=the 1 coupon is 100, point=the 1 point is 10000, cycle=the 1 do2 in oter service - the 1 cycle in order do1}
Or http://localhost:9981/order-info/1
Return: {order=1 order information.... coupon=the 1 coupon is 100, point=the 1 point is 10000}
Visit zipkin-server webui: http://172.20.4.132:9411/
The end!
