Functions

func GetCronMetricSpecsForHPA added in v0.3.0 

func GetCronMetricSpecsForHPA(ehpa *autoscalingapi.EffectiveHorizontalPodAutoscaler) []autoscalingv2.MetricSpec

GetCronMetricSpecsForHPA return a hpa external metric specs from ehpa cron scale specs, this spec will be injected into hpa One ehpa mapping to one cron metric only, even though there are multiple cron specs

func RecordMetrics 

func RecordMetrics(ehpa *autoscalingapi.EffectiveHorizontalPodAutoscaler)
