Functions

func Get

func Get(component interface{}) map[string]string

Get metrics values for provided component type.

func GetAll

func GetAll() map[string]map[string]string

GetAll returns counters for all measured components.

Types

type MeasureFunc

type MeasureFunc func(bufferSize int64)

MeasureFunc captures metrics when buffer is processed.

type ResetFunc

type ResetFunc func() MeasureFunc

ResetFunc returns new Measure closure. This closure is needed to postpone metrics capture until component is actually running.

func Meter

func Meter(component interface{}, sampleRate int) ResetFunc

Meter creates new meter closure to capture component counters.
