* *kubelet_cpu_manager_policy* - If set to `static`, allows pods with certain resource characteristics to be granted increased CPU affinity and exclusivity on the node. And it should be set with `kube_reserved` or `system-reserved`, enable this with the following guide:[Control CPU Management Policies on the Node](https://kubernetes.io/docs/tasks/administer-cluster/cpu-management-policies/)
