Enabling tracing in Jaeger

Note

The article is being updated.

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

Go

  1. package main
  3. import (
  4.     "context"
  5.     "time"
  7.     "github.com/opentracing/opentracing-go"
  8.     jaegerConfig "github.com/uber/jaeger-client-go/config"
  10.     "github.com/ydb-platform/ydb-go-sdk/v3"
  11.     "github.com/ydb-platform/ydb-go-sdk/v3/trace"
  13.     tracing "github.com/ydb-platform/ydb-go-sdk-opentracing"
  14. )
  16. const (
  17.     tracerURL   = "localhost:5775"
  18.     serviceName = "ydb-go-sdk"
  19. )
  21. func main() {
  22.     tracer, closer, err := jaegerConfig.Configuration{
  23.         ServiceName: serviceName,
  24.         Sampler: &jaegerConfig.SamplerConfig{
  25.             Type:  "const",
  26.             Param: 1,
  27.         },
  28.         Reporter: &jaegerConfig.ReporterConfig{
  29.             LogSpans:            true,
  30.             BufferFlushInterval: 1 * time.Second,
  31.             LocalAgentHostPort:  tracerURL,
  32.         },
  33.     }.NewTracer()
  34.     if err != nil {
  35.         panic(err)
  36.     }
  38.     defer closer.Close()
  40.     // set global tracer of this application
  41.     opentracing.SetGlobalTracer(tracer)
  43.     span, ctx := opentracing.StartSpanFromContext(context.Background(), "client")
  44.     defer span.Finish()
  46.     db, err := ydb.Open(
  47.         ctx,
  48.         os.Getenv("YDB_CONNECTION_STRING"),
  49.         tracing.WithTraces(
  50.             tracing.WithDetails(trace.DetailsAll),
  51.         ),
  52.         ydb.WithTraceTable(tracing.Table(
  53.             tracing.WithDetails(trace.DetailsAll),
  54.         )),
  55.     )
  56.     if err != nil {
  57.         panic(err)
  58.     }
  59.     defer func() {
  60.         _ = db.Close(ctx)
  61.     }()
  62. }
