# 配置Sleuth链路追踪
|
|
|
|
配置了Sleuth可以很方便查看微服务的调用路线图,可快速定位问题。
|
|
|
|
SOP基于SpringCloud,因此只要整合[Spring Cloud Sleuth](https://spring.io/projects/spring-cloud-sleuth)即可。
|
|
除此之外,还需要支持dubbo的链路的跟踪,Sleuth在2.0已经对dubbo做了支持,详见:[brave-instrumentation-dubbo-rpc](https://github.com/openzipkin/brave/tree/master/instrumentation/dubbo-rpc)
|
|
|
|
接入Spring Cloud Sleuth步骤如下:
|
|
|
|
- 下载zipkin服务器
|
|
|
|
以mac环境为例,执行下面命令,下载jar并启动zipkin服务
|
|
|
|
```
|
|
curl -sSL https://zipkin.io/quickstart.sh | bash -s
|
|
java -jar zipkin.jar
|
|
```
|
|
|
|
默认端口是9411,更多安装方式详见:[quickstart](https://zipkin.io/pages/quickstart.html)
|
|
|
|
- sop-gateway/pom.xml添加依赖
|
|
|
|
```xml
|
|
<!--开启zipkin服务链路跟踪-->
|
|
<dependency>
|
|
<groupId>org.springframework.cloud</groupId>
|
|
<artifactId>spring-cloud-starter-zipkin</artifactId>
|
|
</dependency>
|
|
```
|
|
|
|
配置文件新增
|
|
|
|
```properties
|
|
# zipkin服务跟踪
|
|
spring.zipkin.base-url=http://127.0.0.1:9411/
|
|
# 设置sleuth收集信息的比率,默认0.1,最大是1,数字越大越耗性能
|
|
spring.sleuth.sampler.probability=1
|
|
```
|
|
重启sop-gateway
|
|
|
|
- 打开sop-story-web/pom.xml
|
|
|
|
添加依赖:
|
|
|
|
```xml
|
|
<!--开启zipkin服务链路跟踪-->
|
|
<dependency>
|
|
<groupId>org.springframework.cloud</groupId>
|
|
<artifactId>spring-cloud-starter-zipkin</artifactId>
|
|
</dependency>
|
|
<!-- zipkin支持dubbo -->
|
|
<dependency>
|
|
<groupId>io.zipkin.brave</groupId>
|
|
<artifactId>brave-instrumentation-dubbo-rpc</artifactId>
|
|
<version>5.6.6</version>
|
|
</dependency>
|
|
```
|
|
|
|
配置文件新增:
|
|
|
|
```properties
|
|
# zipkin服务跟踪
|
|
spring.zipkin.base-url=http://127.0.0.1:9411/
|
|
# 设置sleuth收集信息的比率,默认0.1,最大是1,数字越大越耗性能
|
|
spring.sleuth.sampler.probability=1
|
|
# dubbo使用zipkin过滤器
|
|
dubbo.provider.filter=tracing
|
|
dubbo.consumer.filter=tracing
|
|
```
|
|
|
|
重启服务
|
|
|
|
- 打开sop-book/sop-book-web/pom.xml
|
|
|
|
步骤同上
|
|
|
|
- 运行DubboDemoTest.java单元测试
|
|
|
|
运行完毕看控制台,找到日志信息
|
|
|
|
```text
|
|
2019-07-18 16:22:04.438 INFO [story-service,59dae98250b276bd,60828035658f175f,true] 90553 --- [:12345-thread-2] c.g.s.s.service.DefaultDemoService : dubbo provider, param: DemoParam(id=222)
|
|
```
|
|
|
|
日志内容多了`[story-service,59dae98250b276bd,60828035658f175f,true]`部分,这些是zipkin加进去的,说明如下:
|
|
|
|
```text
|
|
story-service:服务名称
|
|
59dae98250b276bd:traceId
|
|
60828035658f175f:spanId
|
|
true:是否上传到zipkin服务器
|
|
```
|
|
|
|
查看各个服务的控制台,可以发现traceId是一致的。
|
|
|
|
- 浏览器打开:http://127.0.0.1:9411/
|
|
|
|
将traceId复制黏贴到右上角文本框进行查询,可看到服务调用链。
