spring cloud zipkin micrometer

一链路追踪

1.1 链路追踪概念

链路追踪是在微服务中，一个请求经过的节点服务，每个服务的耗时，执行状态的完美展现。

其中使用micrometer

1.2 链路追踪的原理

通过traceid标记整个请求的唯一性；通过spanid标记本节点要发送的内容，通过parentid记录上一个节点。

1.3 ZIPkin的介绍

zipkin是一种分布式链路跟踪系统图形化工具。开发人员能够从zipkin中分析出调用链路中的性能瓶颈，识别出存在问题的应用程序，进而定位问题和解决问题。

二 micrometer+zipkin实现链路追踪

2.1 zipkin服务启动

1.程序包

2.服务启动：java -jar zipkin-server-2.23.4-exec.jar

3.页面查看：http://localhost:9411/zipkin/
