## 1.介绍 ##

[https://spring.io/projects/spring-cloud-sleuth][https_spring.io_projects_spring-cloud-sleuth]

随着系统规模越来越大，微服务之间调用关系变得错综复杂，一条调用链路中可能调用多个微服务，任何一个微服务不可用都可能造整个调用过程失败。

Spring Cloud Sleuth为 Spring Cloud 实现了分布式跟踪解决方案，可以**跟踪**调用链路，分析链路中每个节点的执行情况。

Zipkin 是一个分布式跟踪系统。它有助于**收集**解决服务体系结构中的延迟问题所需的时序数据。功能包括该数据的收集和查找。  
如果日志文件中有跟踪ID，则可以直接跳至该跟踪ID。否则，您可以根据服务，操作名称，标签和持续时间等属性进行查询。将为您总结一些有趣的数据，例如在服务中花费的时间百分比以及操作是否失败。

## 2.**Zipkin安装** ##

**Zipkin下载：**

**Zipkin启动：**

docker run -itd -p 9411:9411 \
    -v /root/docker/zipkin-server/jar/:/root/docker/zipkin-server/jar/ \
    --name zipkin-test openjdk:8u111 java -jar /root/docker/zipkin-server/jar/zipkin-server-2.21.6-exec.jar

**或者docker拉取镜像启动**

**pom**

<dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-zipkin</artifactId>
            </dependency>

**链路数据抽样比例**

默认 10% 的链路数据会被发送到 zipkin 服务。可以配置修改抽样比例

**yml**

#链路追踪和收集
