# Enabling tracing in Jaeger

Below are examples of code for enabling tracing in Jaeger in different YDB SDKs.

{% list tabs %}

- C++

  The functionality is not supported at the moment.

- Go

  {% list tabs %}

  - Native SDK

      ```go
      package main

      import (
          "context"
          "time"

          "github.com/opentracing/opentracing-go"
          jaegerConfig "github.com/uber/jaeger-client-go/config"

          "github.com/ydb-platform/ydb-go-sdk/v3"
          "github.com/ydb-platform/ydb-go-sdk/v3/trace"

          tracing "github.com/ydb-platform/ydb-go-sdk-opentracing"
      )

      const (
          tracerURL   = "localhost:5775"
          serviceName = "ydb-go-sdk"
      )

      func main() {
          tracer, closer, err := jaegerConfig.Configuration{
              ServiceName: serviceName,
              Sampler: &jaegerConfig.SamplerConfig{
                  Type:  "const",
                  Param: 1,
              },
              Reporter: &jaegerConfig.ReporterConfig{
                  LogSpans:            true,
                  BufferFlushInterval: 1 * time.Second,
                  LocalAgentHostPort:  tracerURL,
              },
          }.NewTracer()
          if err != nil {
              panic(err)
          }

          defer closer.Close()

          // set global tracer of this application
          opentracing.SetGlobalTracer(tracer)
