func Meter ¶

func Meter(name string) metric.Meter

Meter gets a named Meter interface. If the name is an empty string, the provider uses a default name.

This is short for MeterProvider().Meter(name)

func MeterProvider ¶

func MeterProvider() metric.Provider

MeterProvider returns the registered global meter provider. If none is registered then a default meter provider is returned that forwards the Meter interface to the first registered Meter.

Use the meter provider to create a named meter. E.g.

meter := global.MeterProvider().Meter("example.com/foo")

or

meter := global.Meter("example.com/foo")

func Propagators ¶

func Propagators() propagation.Propagators

Propagators returns the registered global propagators instance. If none is registered then an instance of propagators.NoopPropagators is returned.

func SetMeterProvider ¶

func SetMeterProvider(mp metric.Provider)

SetMeterProvider registers `mp` as the global meter provider.

func SetPropagators ¶

func SetPropagators(p propagation.Propagators)

SetPropagators registers `p` as the global propagators instance.

func SetTraceProvider ¶

func SetTraceProvider(tp trace.Provider)

SetTraceProvider registers `tp` as the global trace provider.

func TraceProvider ¶

func TraceProvider() trace.Provider

TraceProvider returns the registered global trace provider. If none is registered then an instance of trace.NoopProvider is returned.

Use the trace provider to create a named tracer. E.g.

tracer := global.TraceProvider().Tracer("example.com/foo")

or

tracer := global.Tracer("example.com/foo")

func Tracer ¶

func Tracer(name string) trace.Tracer

Tracer creates a named tracer that implements Tracer interface. If the name is an empty string then provider uses default name.

This is short for TraceProvider().Tracer(name)
