zipkin是一种分布式跟踪系统。它有助于收集解决微服务架构中延迟问题所需的时序数据。它管理这些数据的收集和查找。zipkin的设计基于 google dapper论文。
应用程序用于向zipkin报告时间数据。zipkin用户界面还提供了一个依赖关系图,显示每个应用程序有多少跟踪请求。如果您正在解决延迟问题或错误问题,则可以根据应用程序,跟踪长度,注释或时间戳过滤或排序所有跟踪。选择跟踪后,您可以看到每个跨度所需的总跟踪时间百分比,从而可以识别问题应用程序。
这是翻译过来的原意,自己在这里想如果有个调用链,我们自己该怎么实现。要去质疑任何代码。
官方流程图:最关键的是transport这个地方,通过几种方式传输给conllector。如何在这里支持多种协议,有兴趣的可以进去看看源码。
开始示例,在这里通过一个项目调用不同的方法来进行测试。
先下载zipkin的web ui,通过java -jar zipkin.jar执行

项目启动后,访问http://localhost:9000/zipkintest/server1/zipkin 就可以看到
你好,欢迎进入zipkin的世界
我们通过http://localhost:9411/zipkin 查看zipkin的web ui
查看每条调用链的详情
后面还会讲关于zipkin将数据整合到mysql、elasticsearch中去。
以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持服务器之家。
