Package io.opentelemetry.contrib.awsxray.propagator

Class AwsXrayLambdaPropagator

java.lang.Object

io.opentelemetry.contrib.awsxray.propagator.AwsXrayLambdaPropagator

All Implemented Interfaces:

io.opentelemetry.context.propagation.TextMapPropagator

public final class AwsXrayLambdaPropagator
extends Object
implements io.opentelemetry.context.propagation.TextMapPropagator

Implementation of the AWS X-Ray Trace Header propagation protocol but with special handling for Lambda's _X_AMZN_TRACE_ID environment variable and com.amazonaws.xray.traceHeader system property.

To register the X-Ray propagator together with default propagator when using the SDK:

 OpenTelemetrySdk.builder()
   .setPropagators(
     ContextPropagators.create(
         TextMapPropagator.composite(
             W3CTraceContextPropagator.getInstance(),
             AwsXrayLambdaPropagator.getInstance())))
    .build();
