HPA CPU Initialization Period

During HPA CPU initialization period, HPA can only utilize the metrics of a pod if the pod is ready and its latest metric collection is finished.

You can use this parameter to filter out unstable CPU usage data during the early stage of pod startup. This helps prevent incorrect scaling decisions based on momentary peak values.

For details, see the official documentation.

Suggestions

If HPA makes an incorrect scaling decision due to fluctuating CPU usage during pod startup, increase the value of this parameter.

Possible Risks

Setting this parameter to a small value may trigger unnecessary scaling based on peak CPU usage. Setting it to a large value may cause scaling to be delayed.
