OptionalcustomTraceHeader: stringOptionalconfig: JaegerPropagatorConfigGiven a Context and a carrier, extract context values from a
carrier and return a new context, created from the old context, with the
extracted values.
the Context from which to extract values to transmit over the wire.
the carrier of propagation fields, such as http request headers.
an optional TextMapGetter. If undefined, keys will be all own properties, and keys will be accessed by direct object access.
Return a list of all fields which may be used by the propagator.
Injects values from a given Context into a carrier.
OpenTelemetry defines a common set of format values (TextMapPropagator),
and each has an expected carrier type.
the Context from which to extract values to transmit over the wire.
the carrier of propagation fields, such as http request headers.
an optional TextMapSetter. If undefined, values will be set by direct object assignment.
Propagates SpanContext through Trace Context format propagation. {trace-id}:{span-id}:{parent-span-id}:{flags} {trace-id} 64-bit or 128-bit random number in base16 format. Can be variable length, shorter values are 0-padded on the left. Value of 0 is invalid. {span-id} 64-bit random number in base16 format. {parent-span-id} Set to 0 because this field is deprecated. {flags} One byte bitmap, as two hex digits. Inspired by jaeger-client-node project.
Deprecated
Use W3CTraceContextPropagator from
@opentelemetry/coreinstead. The Jaeger propagator is deprecated by the OpenTelemetry specification. This package will be removed in a future major release.
