We need more information about your cluster configuration to be able to assist you.

Start with your hardware configuration, how you are collecting the metrics, whether your cluster is in Kubernetes, and any other relevant info you can provide.

Please edit your original question and post these information in the question body (please don't post them as an "answer"). Cheers!
