During October 2025, Hao Zhao enhanced observability for Kubernetes environments by developing resource quota metrics features across the newrelic/helm-charts and newrelic/nri-kubernetes repositories. He implemented resource quota metrics export in low-data mode for the nr-k8s-otel-collector Helm chart, introducing a new configuration option and updating documentation, tests, and chart versions. In parallel, Hao expanded the nri-kubernetes integration to collect and parse resource quota data from cAdvisor, broadening metrics coverage for multiple Kubernetes components. His work, primarily using Go and YAML, improved system monitoring and cost awareness, with thorough updates to documentation and CI pipelines to ensure reliability and maintainability.
