InstrumentHandlerFuncWithOpts works like InstrumentHandlerFunc (and shares the same issues) but provides more flexibility (at the cost of a more complex call syntax).

Register registers the provided Collector with the DefaultRegisterer.

RegisterOrGet registers the provided Collector with the DefaultRegisterer and returns the Collector, unless an equal Collector was registered before, in which case that Collector is returned.

SetMetricFamilyInjectionHook replaces the DefaultGatherer with one that gathers from the previous DefaultGatherers but then merges the MetricFamily protobufs returned from the provided hook function with the MetricFamily protobufs returned from the original DefaultGatherer.

UninstrumentedHandler returns an HTTP handler for the DefaultGatherer.

Unregister removes the registration of the provided Collector from the DefaultRegisterer.

DefBuckets are the default Histogram buckets.

DefObjectives are the default Summary quantile values.

AlreadyRegisteredError is returned by the Register method if the Collector to be registered has already been registered before, or a different Collector that collects the same metrics has been registered before.

CounterVec is a Collector that bundles a set of Counters that all share the same Desc, but have different values for their variable labels.
