# Enabling tracing in Jaeger

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

- C++

  This feature is not currently supported.

- Go

  - 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)

        span, ctx := opentracing.StartSpanFromContext(context.Background(), "client")
        defer span.Finish()

        db, err := ydb.Open(ctx,
            os.Getenv("YDB_CONNECTION_STRING"),
            tracing.WithTraces(tracing.WithDetails(trace.DetailsAll)),
        )

            panic(err)
