Reactor Netty

OpenTelemetry Java agent instrumentation

This instrumentation enables HTTP client spans and HTTP client metrics for the Reactor Netty HTTP client.

Name: reactor-netty-1.0
Scope: io.opentelemetry.reactor-netty-1.0
Target versions: io.projectreactor.netty:reactor-netty-http:[1.0.0,), io.projectreactor.netty:reactor-netty:[1.0.0,)
Library: https://projectreactor.io/docs/netty/release/reference/

Telemetry

Metrics: http.client.request.duration
Span attributes: error.type, http.request.method, http.request.method_original, http.request.resend_count, http.response.status_code, network.peer.address, network.peer.port, network.protocol.version, peer.service, server.address, server.port, url.full, service.peer.name

Configuration

Option	Type	Default	Description
`otel.instrumentation.common.peer-service-mapping`	map		Used to specify a mapping from host names or IP addresses to peer services.
`otel.instrumentation.http.client.capture-request-headers`	list		List of HTTP request headers to capture in HTTP client telemetry.
`otel.instrumentation.http.client.capture-response-headers`	list		List of HTTP response headers to capture in HTTP client telemetry.
`otel.instrumentation.http.client.emit-experimental-telemetry`	boolean	false	Enable the capture of experimental HTTP client telemetry. Adds the `http.request.body.size` and `http.response.body.size` attributes to spans, and records `http.client.request.body.size` and `http.client.response.body.size` metrics.
`otel.instrumentation.http.known-methods`	list	CONNECT,DELETE,GET,HEAD,OPTIONS,PATCH,POST,PUT,TRACE	Configures the instrumentation to recognize an alternative set of HTTP request methods. All other methods will be treated as `_OTHER`.
`java.common.http.client.url_template_rules`	list		Rules for deriving low-cardinality URL templates (routes) from HTTP client request URLs. Only applied when experimental HTTP client telemetry is enabled.
`otel.instrumentation.reactor-netty.connection-telemetry.enabled`	boolean	false	Enables the creation of Connect and DNS spans.
`otel.instrumentation.sanitization.url.experimental.sensitive-query-parameters`	list	AWSAccessKeyId,Signature,sig,X-Goog-Signature	List of URL query parameter names whose values are redacted in URL attributes. See https://opentelemetry.io/docs/specs/semconv/http/http-spans.
