Functions

func NewExecutionTimer

func NewExecutionTimer() *metrics.ExecutionTimer

NewExecutionTimer provides a timer for Recommender's RunOnce execution

func ObserveRecommendationLatency

func ObserveRecommendationLatency(created time.Time)

ObserveRecommendationLatency observes the time it took for the first recommendation to appear

func RecordAggregateContainerStatesCount

func RecordAggregateContainerStatesCount(statesCount int)

RecordAggregateContainerStatesCount records the number of containers being tracked by the recommender

func RecordMetricsServerResponse
