kubectl describe node node-name

gives us a summary of cpu requests and limits

Resource           Requests              Limits
--------           --------              ------
cpu                3449m (98%)           20700m (591%)
                           ↑

Im trying to get the CPU Requests % from Prometheus Metrics with PromQL in Grafana

I can get the CPU requests Total and sum it by node with

sum by (node) (kube_pod_container_resource_requests_cpu_cores) 

not sure how to plug kube_node_status_allocatable_cpu_cores here which gives me allocatable cpu for each node. Note all my nodes have the some number of cores.

How to mix node and container metrics in one query?
