Types ¶
type ContinuousFactory ¶
type ContinuousFactory struct{}
ContinuousFactory implements the Factory interface by returning a continuous time meter.
type Factory ¶
type Factory interface { // New returns a new meter with the provided halflife. New(halflife time.Duration) Meter }
Factory returns new meters.
type IntervalFactory ¶
type IntervalFactory struct{}
IntervalFactory implements the Factory interface by returning an interval based meter.
type Meter ¶
type Meter interface { // Start the meter, the read value will be monotonically increasing while // the meter is running. Start(time.Time) // Stop the meter, the read value will be exponentially decreasing while the // meter is off. Stop(time.Time) // Read the current value of the meter, this can be used to approximate the // percent of time the meter has been running recently. The definition of // recently depends on the halflife of the decay function. Read(time.Time) float64 }
Meter tracks a continuous exponential moving average of the % of time this meter has been running.
func NewIntervalMeter ¶
NewIntervalMeter returns a new Meter with the provided halflife
