Functions ¶
func InitTracer ¶ added in v0.8.1
func InitTracer(log logrus.FieldLogger, cfg *config.Config, serviceName string) func(context.Context) error
InitTracer initializes OpenTelemetry tracing using the provided config. It sets the global TracerProvider, which will be used for all span creation throughout the application. If tracing is disabled or misconfigured, a no-op tracer provider is used instead.
The returned shutdown function should be called on application exit to ensure all spans are flushed.
func NewLoggingResponseWriter ¶
func NewLoggingResponseWriter(w http.ResponseWriter) *loggingResponseWriter
func StartSpan ¶ added in v0.8.1
func StartSpan(ctx context.Context, tracerName, spanName string, opts ...trace.SpanStartOption) (context.Context, trace.Span)
StartSpan creates a new span using the global tracer provider. It uses the provided context to determine the parent span (if any), and returns a new context and the started span. The span name is normalized to kebab-case.
