type Calculator ¶
type Calculator interface {
GetUsageRatioReplicaCount(currentReplicas int32, usageRatio float64, readyPodCount int64) int32
GetPlainMetricReplicaCount(metrics podmetrics.MetricsInfo,
currentReplicas int32,
targetUtilization int64,
readyPodCount int64,
missingPods,
ignoredPods sets.String) int32
}
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
