Class HttpClientAttributesExtractor<REQUEST,RESPONSE>

java.lang.Object

io.opentelemetry.instrumentation.api.instrumenter.http.HttpClientAttributesExtractor<REQUEST,RESPONSE>

All Implemented Interfaces:

io.opentelemetry.instrumentation.api.instrumenter.AttributesExtractor<REQUEST,RESPONSE>, io.opentelemetry.instrumentation.api.internal.SpanKeyProvider

public final class HttpClientAttributesExtractor<REQUEST,RESPONSE>
extends Object
implements io.opentelemetry.instrumentation.api.internal.SpanKeyProvider

Extractor of HTTP client attributes. Instrumentation of HTTP client frameworks should extend this class, defining HttpClientAttributesExtractor and HttpClientAttributesExtractor with the actual request / response types of the instrumented library. If an attribute is not available in this library, it is appropriate to return null from the protected attribute methods, but implement as many as possible for best compliance with the OpenTelemetry specification.

Method Summary

Modifier and Type	Method	Description
static <REQUEST, RESPONSE> HttpClientAttributesExtractorBuilder<REQUEST,RESPONSE>	builder(HttpClientAttributesGetter<REQUEST,RESPONSE> getter)	Returns a new HttpClientAttributesExtractorBuilder that can be used to configure the HTTP client attributes extractor.
static <REQUEST, RESPONSE> HttpClientAttributesExtractor<REQUEST,RESPONSE>	create(HttpClientAttributesGetter<REQUEST,RESPONSE> getter)	Creates the HTTP client attributes extractor with default configuration.
io.opentelemetry.instrumentation.api.internal.SpanKey	internalGetSpanKey()	This method is internal and is hence not for public use.
void	onEnd(io.opentelemetry.api.common.AttributesBuilder attributes, io.opentelemetry.context.Context context, REQUEST request, RESPONSE response, Throwable error)
