Package io.opentelemetry.extension.trace.propagation

Class OtTracePropagator

java.lang.Object

io.opentelemetry.extension.trace.propagation.OtTracePropagator

All Implemented Interfaces:

io.opentelemetry.context.propagation.TextMapPropagator

@Immutable
public final class OtTracePropagator
extends Object
implements io.opentelemetry.context.propagation.TextMapPropagator

Implementation of the protocol used by OpenTracing Basic Tracers. Context is propagated through 3 headers, ot-tracer-traceid, ot-tracer-span-id, and ot-tracer-sampled. IDs are sent as hex strings and sampled is sent as true or false. Baggage values are propagated using the ot-baggage- prefix. See OT Python Propagation TextMapPropagator.
