Priyanka Saggu, Mario Jason Braganza
KubeCon + CloudNativeCon Europe 2025 · Session
In this insightful KubeCon EU talk, Priyanka Saggu and Mario Jason Braganza presented a unique methodology for understanding the intricate workings of Kubernetes: by dissecting the vast array of metrics it exposes. Titled "Learning Kubernetes Through the Lens of Metrics," their presentation served as a spiritual successor to their previous talk on Kubernetes Enhancement Proposals (KEPs), continuing their exploration of Kubernetes internals through unconventional yet highly effective lenses. The speakers posited that rather than relying solely on documentation or high-level overviews, diving deep into the raw data points generated by Kubernetes components can reveal profound insights into its architecture, operational state, and feature landscape.

This talk presents a highly effective and novel methodology for understanding Kubernetes internals by systematically dissecting its vast metric landscape. The speakers demonstrated how raw operational data points from components like the API server, Kubelet, Scheduler, and Etcd can reveal profound insights into feature enablement, resource management, and complex internal mechanisms. This approach is not just for monitoring but serves as a powerful learning tool, offering practical, actionable knowledge for anyone seeking a deeper, data-driven grasp of Kubernetes.
