Jaeger propagator for OpenTelemetry

Usage

package main

import (
        "net/http"

        prop "github.com/seankhliao/otel-jaeger-propagator"
        "go.opentelemetry.io/otel/api/global"
        "go.opentelemetry.io/otel/api/propagation"
)

func main() {
        // global propagation
        global.SetPropagators(
                propagation.WithExtractors(prop.DefaultJaeger),
                propagation.WithInjectors(prop.DefaultJaeger),
        )
}

Propagation format

{trace-id}:{span-id}:{parent-span-id}:{flags}

Propagation is mapped to the core.SpanContext fields:

• trace-id: SpanContext.TraceID
• span-oid: SpanContext.SpanID
• parent-span-id: ignored, injected as 0
• flags: SpanContext.TraceFlags
  • 0x01 is mapped to core.TraceFlagsSampled
  • all other flags are ignored
