介绍

Zipkin是一个分布式跟踪系统，用来收集微服务架构中的时序数据以用于调用链分析。Zipkin提供了In-Memory、MySql、Elasticsearch等存储方式。

安装配置

服务端安装
开发环境中，我们可以安装一个In-Memory的Zipkin

docker run -d -p 9411:9411 openzipkin/zipkin

安装完成后打开：https://localhost:9411/zipkin/可见：

更多Docker部署方式见：zipkin-docker

.NET下的使用

Install-Package zipkin4net -Version 1.3.0
Install-Package zipkin4net.middleware.aspnetcore -Version 1.3.0

在ServiceA中添加注册代码：

public void RegisterZipkinTrace(IApplicationBuilder app, ILoggerFactory loggerFactory, IHostApplicationLifetime lifetime) {     lifetime.ApplicationStarted.Register(() => {         TraceManager.SamplingRate = 1.0f; var logger = new TracingLogger(loggerFactory, "zipkin4net"); var httpSender = new HttpZipkinSender("https://localhost:9411", "application/json"); var tracer = new ZipkinTracer(httpSender, new JSONSpanSerializer(), new Statistics()); var consoleTracer = new zipkin4net.Tracers.ConsoleTracer();          TraceManager.RegisterTracer(tracer);         TraceManager.RegisterTracer(consoleTracer);         TraceManager.Start(logger); });      lifetime.ApplicationStopped.Register(() => TraceManager.Stop());     app.UseTracing("service_a"); } 

配置到管道中

public void Configure(IApplicationBuilder app,ILoggerFactory loggerFactory, IHostApplicationLifetime lifetime) { RegisterZipkinTrace(app, loggerFactory, lifetime); } 

ServiceB也是同样的操作
我们请求一次获取文章列表接口
