Functions

func Init

func Init(opts ...func(*options)) (func(context.Context) error, error)

Init initialises the global tracer via the option(s) defaulting to a noop tracer.

func Start

func Start(ctx context.Context, spanName string, opts ...trace.SpanStartOption) (context.Context, trace.Span)

Start creates a span and a context.Context containing the newly-created span from the global tracer. See go.opentelemetry.io/otel/trace#Start for more details.

func WithJaeger

func WithJaeger(addr string) func(*options)

WithJaeger returns an option to configure an OpenTelemetry tracing exporter for Jaeger.

func WithJaegerOrNoop

func WithJaegerOrNoop(jaegerAddr string) func(*options)

WithJaegerOrNoop returns an option to configure an OpenTelemetry tracing exporter for Jaeger if the address is not empty, else the default noop tracer is retained.

func WithStdOut

func WithStdOut(w io.Writer) func(*options)

WithStdOut returns an option to configure an OpenTelemetry exporter for tracing telemetry to be written to an output destination as JSON.
