Functions ¶

func Meter ¶

func Meter(instrumentationName string, opts ...metric.MeterOption) metric.Meter

Meter returns a Meter from the global MeterProvider. The name must be the name of the library providing instrumentation. This name may be the same as the instrumented code only if that code provides built-in instrumentation. If the name is empty, then a implementation defined default name will be used instead.

If this is called before a global MeterProvider is registered the returned Meter will be a No-op implementation of a Meter. When a global MeterProvider is registered for the first time, the returned Meter, and all the instruments it has created or will create, are recreated automatically from the new MeterProvider.

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

func MeterProvider ¶

func MeterProvider() metric.MeterProvider

MeterProvider returns the registered global meter provider.

If no global MeterProvider has been registered, a No-op MeterProvider implementation is returned. When a global MeterProvider is registered for the first time, the returned MeterProvider, and all the Meters it has created or will create, are recreated automatically from the new MeterProvider.

func SetMeterProvider ¶

func SetMeterProvider(mp metric.MeterProvider)

SetMeterProvider registers mp as the global MeterProvider.
