Types ¶

type TimeoutDetector ¶

type TimeoutDetector struct {
	// contains filtered or unexported fields
}

TimeoutDetector detects routine starvations by observing the actual time duration to finish an action or between two events that should happen in a fixed interval. If the observed duration is longer than the expectation, the detector will report the result.

func NewTimeoutDetector ¶

func NewTimeoutDetector(maxDuration time.Duration) *TimeoutDetector

NewTimeoutDetector creates the TimeoutDetector.

func (*TimeoutDetector) Observe ¶

func (td *TimeoutDetector) Observe(which uint64) (bool, time.Duration)

Observe observes an event for given id. It returns false and exceeded duration if the interval is longer than the expectation.

func (*TimeoutDetector) Reset ¶

func (td *TimeoutDetector) Reset()

Reset resets the NewTimeoutDetector.
