Functions

func Middleware

func Middleware(routes chi.Routes) func(next http.Handler) http.Handler

func NewNoopExporter

func NewNoopExporter() trace.SpanExporter

func NewZerologExporter

func NewZerologExporter(logger *zerolog.Logger) trace.SpanExporter

func StartSpan

func StartSpan(ctx context.Context, spanName string, opts ...otrace.SpanStartOption) (context.Context, otrace.Span)

StartSpan wraps starting a tracing span. This makes sure we start spans only when Telemetry is enabled.

It also wraps fetching the Tracer, which is a bit confusing, but its name is just for distinguishing different Tracers, we have not identified need for multiple tracers in our code yet. We use empty name, it should be safe according to https://pkg.go.dev/go.opentelemetry.io/otel/trace@v1.16.0#TracerProvider
