Doing a kubectl describe node I get:
[...]
Allocated resources:
(Total limits may be over 100 percent, i.e., overcommitted.)
Resource Requests Limits
-------- -------- ------
cpu 14095m (56%) 48794m (195%)
memory 28669Mi (12%) 50824Mi (21%)
ephemeral-storage 22342Mi (41%) 34558Mi (64%)
hugepages-1Gi 0 (0%) 0 (0%)
hugepages-2Mi 0 (0%) 0 (0%)
Which "total" value is it taking for calculating the percentage for each of the resources?
For example, I'm taking the cpu Request value by summing all the values from the previous "CPU Request" in the "Non-terminated Pods" section, but I realized the percentage is not the direct result of summing each of the corresponding pods percentages.
In Kubernetes, the percentages displayed in the kubectl describe node command under Allocated resources are calculated based on the node's total available resources. The percentages represent how much of the node's total CPU, memory, ephemeral storage, or hugepages resources are requested or limited by the pods running on that node.
The percentages shown are calculated based on the allocatable values of the node, i.e. available after reserving resources for K8S and system components.
In you case :
Requests: 14095m (56%) : This means that the sum of CPU requests across all pods on this node is 14095m (which is 14.095 CPU cores).
The (56%) indicates that this 14095m is 56% of the total CPU capacity of the node.
Limits: 48794m (195%): This indicates that the sum of CPU limits across all pods on this node is 48794m (which is 48.794 CPU cores). The (195%) indicates that this 48794m exceeds the node's total CPU capacity by 95%, meaning the node is overcommitted on CPU.
