Calculator is used to calculate replica counts

type ReplicaCalculator

type ReplicaCalculator struct {
	Tolerance float64
}

ReplicaCalculator uses a tolerance provided to calculate replica counts for scaling up/down/remaining the same

func (*ReplicaCalculator) GetPlainMetricReplicaCount

func (r *ReplicaCalculator) GetPlainMetricReplicaCount(metrics podmetrics.MetricsInfo,
	currentReplicas int32,
	targetUtilization int64,
	readyPodCount int64,
	missingPods,
	ignoredPods sets.String) int32

GetPlainMetricReplicaCount calculates the replica count based on the metrics of each pod and a target utilization, providing a different replica count if the calculated usage ratio is beyond the tolerance

func (*ReplicaCalculator) GetUsageRatioReplicaCount

func (r *ReplicaCalculator) GetUsageRatioReplicaCount(currentReplicas int32, usageRatio float64, readyPodCount int64) int32

GetUsageRatioReplicaCount calculates the replica count based on the number of replicas, number of ready pods and the usage ratio of the metric - providing a different value if beyond the tolerance
