Kubernetes autoscaler targetCPUUtilizationPercentage

This is average cpu utilisation of all the pods, so if you have given CPU as 200 in the resource requests and targetCPUUtilizationPercentage as 80%, then at 160 value of threshold, it will scale out the pod. It will create a new repliace.

The CPU utilization is the average CPU usage of a all pods in a deployment across the last minute divided by the requested CPU of this deployment. If the mean of the pods' CPU utilization is higher than the target you defined, the your replicas will be adjusted.
