假设我们在demo命名空间中部署了下面的HPA(HorizontalPodAutoscaler)，并且此demo命名空间中的多个Pod(POD-A、POD-B)具有相同的指标“istio_Requestsper_Second”，HPA如何确定应该使用Pod的指标“istio_Requestsper_Second”？或者，每个具有此指标的POD都将对照HPA目标进行评估？

apiVersion: autoscaling/v2beta2
kind: HorizontalPodAutoscaler
metadata:
  name: httpbin
spec:
  minReplicas: 1
  maxReplicas: 5
  metrics:
  - type: Pods
    pods:
      metric:
        name: istio_requests_per_second
      target:
        type: AverageValue
        averageValue: "10"
  scaleTargetRef:
    apiVersion: apps/v1
    kind: Deployment
    name: httpbin

测试..。
