Functions

func MuxServerMiddleware

func MuxServerMiddleware(serviceName string) func(http.Handler) http.Handler

MuxServerMiddleware returns middleware that should be attached to a gorilla/mux server. It does two things: starts spans, and adds span/trace info to the request-specific logger. Right now we only support logging IDs in the format that Datadog expects.

func SetupGlobalTraceProviderAndExporter

func SetupGlobalTraceProviderAndExporter(ctx context.Context) (sdktrace.SpanExporter, *sdktrace.TracerProvider, error)

SetupGlobalTraceProviderAndExporter sets up the global trace provider and exporter.

func SetupGlobalTraceProviderAndExporterForTest

func SetupGlobalTraceProviderAndExporterForTest() (*tracetest.InMemoryExporter, *sdktrace.TracerProvider, error)

SetupGlobalTraceProviderAndExporterForTest is meant to be used in unit testing, and mirrors the setup above for outside of unit testing. It returns an in-memory exporter for examining generated spans.
