Types ¶

type Provider ¶

type Provider interface {
	NewCounter(name, help string) metrics.Counter
	NewHistogram(name, help string, min, max int64, sigfigs int, quantiles ...int) (metrics.Histogram, error)
	NewGauge(name, help string) metrics.Gauge
	Stop()
}

Provider represents a union set of constructors and lifecycle management functions for each supported metrics backend. It should be used by those who need to easily swap out implementations, e.g. dynamically, or at a single point in an intermediating framework.

func NewDiscardProvider ¶

func NewDiscardProvider() Provider

NewDiscardProvider returns a provider that will discard all metrics.

func NewDogStatsdProvider ¶

func NewDogStatsdProvider(network, address, prefix string, interval time.Duration, logger log.Logger) (Provider, error)

NewDogStatsdProvider will return a Provider implementation that is a simple wrapper around a dogstatsd.Emitter. All metric names will be prefixed with the given value and data will be emitted once every interval or when the buffer has reached its max size. If no network value is given, it will default to "udp".

func NewExpvarProvider ¶

func NewExpvarProvider(prefix string) Provider

NewExpvarProvider is a very thin wrapper over the expvar package. If a prefix is provided, it will prefix all metric names.

func NewGraphiteProvider ¶

func NewGraphiteProvider(network, address, prefix string, interval time.Duration, logger log.Logger) (Provider, error)

NewGraphiteProvider will return a Provider implementation that is a simple wrapper around a graphite.Emitter. All metric names will be prefixed with the given value and data will be emitted once every interval. If no network value is given, it will default to "udp".

func NewPrometheusProvider ¶

func NewPrometheusProvider(namespace, subsystem string) Provider

NewPrometheusProvider returns a Prometheus provider that uses the provided namespace and subsystem for all metrics.

func NewStatsdProvider ¶

func NewStatsdProvider(network, address, prefix string, interval time.Duration, logger log.Logger) (Provider, error)

NewStatsdProvider will return a Provider implementation that is a simple wrapper around a statsd.Emitter. All metric names will be prefixed with the given value and data will be emitted once every interval or when the buffer has reached its max size. If no network value is given, it will default to "udp".
