Functions

func EndError

func EndError(span trace.Span, err error)

EndError ends the span with a status of "error".

func EndOK

func EndOK(span trace.Span)

EndOK ends the span with a status of "ok".

func Initialize

func Initialize(conn *grpc.ClientConn) (func(context.Context) error, error)

Initialize initializes the OpenTelemetry tracing library.

func IsInitialized

func IsInitialized() bool

IsInitialized returns true if the tracer has been successfully initialized.

func New

func New(spanCtx context.Context, spanName string, kind trace.SpanKind, attributes ...attribute.KeyValue) (ctx context.Context, span trace.Span)

New starts a new span with the given name and returns the context and span. If spanCtx is nil, context.Background() is used. The arg kind is used to set the span kind. The constant trace.SpanKind is defined here: https://pkg.go.dev/go.opentelemetry.io/otel/trace@v1.15.1#SpanKind

func TracingMiddleware

func TracingMiddleware() gin.HandlerFunc
