如何从C＃向Jaeger发送跟踪？

如何解决如何从C＃向Jaeger发送跟踪？

我正在尝试使用Jaeger包从C＃应用程序向Jaeger发送跟踪。

jaeger-client-csharp文档中没有最少的示例，但是从我的阅读中，我认为这应该可行。

using Jaeger;
using Jaeger.Samplers;

namespace jaegertest
{
    class Program
    {
        static void Main(string[] args)
        {
            var tracer = new Tracer.Builder("my-service")
                .WithSampler(new ConstSampler(true))
                .Build();

            using (var scope = tracer.BuildSpan("foo").StartActive(true))
            {
                System.Threading.Thread.Sleep(1000);
            }
        }
    }
}

我正在运行jaeger-all-in-one.exe，但是当我运行此代码时，没有任何新痕迹的迹象。我尝试过手动配置采样器，发送器，报告器等，但是没有任何尝试。我需要添加什么才能使踪迹显示在Jaeger中？

解决方法

这是我能够找到的最简单的工作示例。

using Jaeger;
using Jaeger.Reporters;
using Jaeger.Samplers;
using Jaeger.Senders.Thrift;

namespace jaegertest
{
    class Program
    {
        static void Main(string[] args)
        {
            var tracer = new Tracer.Builder("my-service")
                .WithSampler(new ConstSampler(true))
                .WithReporter(new RemoteReporter.Builder()
                    .WithSender(new UdpSender())
                    .Build())
                .Build();

            using (var scope = tracer.BuildSpan("foo").StartActive(true))
            {
                System.Threading.Thread.Sleep(1000);
            }

            tracer.Dispose();
        }
    }
}

这是一个更实际的示例，该示例从配置中构建跟踪器。

using Jaeger;
using Jaeger.Samplers;
using Jaeger.Senders;
using Jaeger.Senders.Thrift;
using Microsoft.Extensions.Logging;

namespace jaegertest
{
    class Program
    {
        static void Main(string[] args)
        {
            var loggerFactory = new LoggerFactory();

            var samplerConfiguration = new Configuration.SamplerConfiguration(loggerFactory)
                .WithType(ConstSampler.Type)
                .WithParam(1);

            var senderResolver = new SenderResolver(loggerFactory)
                .RegisterSenderFactory<ThriftSenderFactory>();

            var senderConfiguration = new Configuration.SenderConfiguration(loggerFactory)
                .WithSenderResolver(senderResolver);

            var reporterConfiguration = new Configuration.ReporterConfiguration(loggerFactory)
                .WithSender(senderConfiguration)
                .WithLogSpans(true);

            var tracer = (Tracer)new Configuration("my-service",loggerFactory)
                .WithSampler(samplerConfiguration)
                .WithReporter(reporterConfiguration)
                .GetTracer();

            using (var scope = tracer.BuildSpan("foo").StartActive(true))
            {
                System.Threading.Thread.Sleep(1000);
            }

            tracer.Dispose();
        }
    }
}
