func Meter ¶

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

Meter returns a Meter from the global MeterProvider. The instrumentationName 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 instrumentationName is empty, then a implementation defined default name will be used instead.

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

func MeterProvider ¶ added in v0.28.0

func MeterProvider() metric.MeterProvider

MeterProvider returns the registered global trace provider. If none is registered then a No-op MeterProvider is returned.

func SetMeterProvider ¶

func SetMeterProvider(mp metric.MeterProvider)

SetMeterProvider registers `mp` as the global meter provider.
