kubernetes/kube-state-metrics
Jun 2022 - Jan 2023
Add-on agent to generate and expose cluster-level metrics.
Role in this project:Back-end Developer
Back-end DeveloperContributions:13 reviews, 8 commits, 7 PRs in 6 months
Contributions summary:Mario primarily focused on extending the functionality of kube-state-metrics to expose new metrics related to Kubernetes endpoints. They implemented a new metric, `kube_endpoint_address`, and then added a "ready" label to provide more detailed information about endpoint address availability. Further, they graduated new endpoint metrics to STABLE, deprecating older ones, and introduced a flag to manage custom resource monitoring. Their work involved modifying Go code to gather and expose Kubernetes metrics.
