Can Kepler Measure Per Node Energy Consumption?

[JesusdelCas99]

Issue Description

I am working on a project to create a Kubernetes scheduler that makes decisions based on the power efficiency of each node. To achieve this, I need accurate energy consumption metrics for each node in the cluster.

While using Kepler, I can aggregate energy consumption for individual pods running on a node. However, I have noticed that there are two additional namespaces—system and kernel—that account for the energy consumption of system-level processes and the kernel across the entire node.

The problem is that I cannot find a way to disaggregate the energy consumption of these namespaces into per-node metrics. This makes it difficult to obtain a total energy usage figure for each node that includes both pod-level and system/kernel-level energy consumption.

My question is:

• Is there a way to measure the total energy consumption per Kubernetes node, including all processes (pods, system, kernel, etc.)?
• If not, are there any workarounds or planned features in Kepler that might help in capturing this data more accurately at the node level?

Thank you for your help!
