}

InterruptionEvent gives more context of the interruption event

func (*InterruptionEvent) IsRebalanceRecommendation

func (e *InterruptionEvent) IsRebalanceRecommendation() bool

IsRebalanceRecommendation returns true if the interruption event is a rebalance recommendation

func (*InterruptionEvent) TimeUntilEvent

func (e *InterruptionEvent) TimeUntilEvent() time.Duration

TimeUntilEvent returns the duration until the event start time

type Monitor

type Monitor interface {
	Monitor() error
	Kind() string
}

Monitor is an interface which can be implemented for various sources of interruption events
