Types

type Config

type Config interface {
	Registry

	// Details returns bitmask for customize details of NewScope
	// If zero - use full set of driver NewScope
	Details() trace.Details

	// WithSystem returns new Config with subsystem scope
	// Separator for split scopes of NewScope provided Config implementation
	WithSystem(subsystem string) Config
}

type Gauge

type Gauge interface {
	Add(delta float64)
	Set(value float64)
}

Gauge tracks single float64 value.

type GaugeVec

type GaugeVec interface {
	With(map[string]string) Gauge
}

GaugeVec returns Gauge from GaugeVec by lables

type Histogram

type Histogram interface {
	Record(v float64)
}

Histogram tracks distribution of value.

type HistogramVec

type HistogramVec interface {
	With(map[string]string) Histogram
}

HistogramVec stores multiple dynamically created timers

type Registry

type Registry interface {
	// GaugeVec returns GaugeVec by name, subsystem and labels
	// If gauge by args already created - return gauge from cache
	// If gauge by args nothing - create and return newest gauge
	GaugeVec(name string, labelNames ...string) GaugeVec

	// TimerVec returns TimerVec by name, subsystem and labels
	// If timer by args already created - return timer from cache
	// If timer by args nothing - create and return newest timer
	TimerVec(name string, labelNames ...string) TimerVec

	// HistogramVec returns HistogramVec by name, subsystem and labels
	// If histogram by args already created - return histogram from cache
	// If histogram by args nothing - create and return newest histogram
	HistogramVec(name string, buckets []float64, labelNames ...string) HistogramVec
}

type Timer

type Timer interface {
	Record(d time.Duration)
}

Timer tracks distribution of value.

type TimerVec

type TimerVec interface {
	With(map[string]string) Timer
}

TimerVec stores multiple dynamically created timers
