OpenTelemetry.Instrumentation.AspNetCore
OpenTelemetry.Exporter.Zipkin新增配置Endpoint对应Zipkin部署地址Zipkin: {ServiceName: WebApplication1,Endpoint: http://192.168.1.11:9411/api/v2/spans
}修改Startup.cspublic void ConfigureServices(IServiceCollection services)
{...services.AddOpenTelemetryTracing((builder) builder.SetResourceBuilder(ResourceBuilder.CreateDefault().AddService(this.Configuration.GetValuestring(Zipkin:ServiceName))).AddAspNetCoreInstrumentation().AddZipkinExporter(zipkinOptions {zipkinOptions.Endpoint new Uri(Configuration.GetValuestring(Zipkin:Endpoint));}));
}修改WeatherForecastController.cs访问WebApplication2[HttpGet]
public async Taskstring Get()
{var response await _httpClientFactory.CreateClient().GetStringAsync(http://localhost:5200/WeatherForecast);return response;
}WebApplication2引用Nuget包包括预发行版OpenTelemetry.Extensions.Hosting
OpenTelemetry.Instrumentation.AspNetCore
OpenTelemetry.Exporter.Zipkin
Grpc.Net.Client
OpenTelemetry.Instrumentation.GrpcNetClient新增配置Endpoint对应Zipkin部署地址Zipkin: {ServiceName: WebApplication2,Endpoint: http://192.168.1.11:9411/api/v2/spans
}修改Startup.cspublic void ConfigureServices(IServiceCollection services)
{...services.AddOpenTelemetryTracing((builder) builder.SetResourceBuilder(ResourceBuilder.CreateDefault().AddService(this.Configuration.GetValuestring(Zipkin:ServiceName))).AddGrpcClientInstrumentation().AddAspNetCoreInstrumentation().AddZipkinExporter(zipkinOptions {zipkinOptions.Endpoint new Uri(Configuration.GetValuestring(Zipkin:Endpoint));}));
}修改WeatherForecastController.cs访问GrpcService1[HttpGet]
public async Taskstring Get()
{var channel GrpcChannel.ForAddress(http://localhost:5300);var client new Greeter.GreeterClient(channel);var response await client.SayHelloAsync(new HelloRequest { Name World });return response.Message;
}GrpcService1引用Nuget包包括预发行版OpenTelemetry.Extensions.Hosting
OpenTelemetry.Instrumentation.AspNetCore
OpenTelemetry.Exporter.Zipkin新增配置Endpoint对应Zipkin部署地址Zipkin: {ServiceName: GrpcService1,Endpoint: http://192.168.1.11:9411/api/v2/spans
}修改Startup.csprivate IConfiguration Configuration { get; }public Startup(IConfiguration configuration)
{Configuration configuration;
}
public void ConfigureServices(IServiceCollection services)
{...services.AddOpenTelemetryTracing((builder) builder.SetResourceBuilder(ResourceBuilder.CreateDefault().AddService(this.Configuration.GetValuestring(Zipkin:ServiceName))).AddAspNetCoreInstrumentation().AddZipkinExporter(zipkinOptions {zipkinOptions.Endpoint new Uri(Configuration.GetValuestring(Zipkin:Endpoint));}));
}运行效果启动3个应用程序WebApplication1 http://localhost/5100WebApplication2 http://localhost/5200GrpcService1 http://localhost/5300访问WebApplication1后即可在Zipkin上查看调用链结论使用OpenTelemetry搭配Zipkin可以轻松实现监控WebAPI/gRPC调用链。
