简介： 

Spirng Cloud Sleuth 其实是个工具，它在整个分布式系统中能跟踪一个用户请求的过程，捕获这些跟踪数据，就能构建微服务的整个调用链路的视图，这是调试和监控微服务的关键工具。

1. 耗时分析
2. 可视化错误
3. 链路优化

Zipkin是Twitter的一个开源的项目 ，他致力于收集服务的定时数据，以解决微服务架构中的延迟问题，包括数据的收集 存储 查找和展现。

入门：

流程：

1. 安装启动zipkin。 java-jar zipkin.jar
2. 访问zipkin web界面。http://localhost:9411
3. 在服务提供方和消费方分别引入 sleuth和zipkin依赖

cmd界面运行这个jar包 

java -jar .\zipkin-server-2.12.9-exec.jar

 基本代码，生产者和消费者

照着这个搭建一个Eureka-server-sleuth sleuth-cousumer 和sleuth-provider

spirngcloud Eureka服务治理（注册中心）

参考：springcloud代码里的Eureka server模块 cousumer和provider模块 

引入sleuth和zipkin
