Types

type SlidingWindowCounter

type SlidingWindowCounter struct {
	Interval        time.Duration
	SlotGranularity time.Duration
	// contains filtered or unexported fields
}

SlidingWindowCounter is used to count the number of events happened in the last X duration (in terms of a sliding window). Interval defines how big the time window is and SlotGranularity defines how fine grained the counter is.

func NewSlidingWindowCounter

func NewSlidingWindowCounter(i time.Duration, sg time.Duration) *SlidingWindowCounter

NewSlidingWindowCounter creates an instance of SlidingWindowCounter

func NewSlidingWindowCounterWithSecondSlot

func NewSlidingWindowCounterWithSecondSlot(i time.Duration) *SlidingWindowCounter

NewSlidingWindowCounterWithSecondSlot creates an instance of SlidingWindowCounter with the second level slot

func (*SlidingWindowCounter) Count

func (c *SlidingWindowCounter) Count() uint64

Count reads the current gauge. It's a blocking operation.

func (*SlidingWindowCounter) Increment

func (c *SlidingWindowCounter) Increment()

Increment increase the counter by 1. It's a blocking operation.
