• Cloud-Sleuth分布式链路追踪(服务跟踪)

    简介

    在微服务框架中,一个由客户端发起的请求在后端系统中会经过多个不同的服务节点调用来协同产生最后的请求结果,每一个前端请求都会形成一条复杂的分布式服务调用链路,链路中的任何一环出现高延时或错误都会引起整个请求最后的失败

    在分布式系统中提供追踪解决方案并且兼容支持了zipkin(管展现)     Cloud-Sleuth(管监控)

    这么说吧:Cloud把zipkin收编了  然后取名Sleuth

    搭建链路监控

    SpringCloud从F版起已不需要自己构建Zipkin server了，只需要调用jar包即可

    Releases · openzipkin/zipkin · GitHub

    我这边用的

    Release 2.12.9 · openzipkin/zipkin · GitHub

    jar  maven仓库下载

    Central Repository: io/zipkin/zipkin-servericon-default.png?t=N7T8https://repo1.maven.org/maven2/io/zipkin/zipkin-server/

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