Our Journey Taking Kubernetes State Metrics to the Next Level

Datadog, a company that provides monitoring services for cloud-based applications, has contributed to the improvement of kube-state-metrics (KSM), an open source Kubernetes service. The contribution aimed at enhancing the scalability and extensibility of KSM by reducing the time spent collecting metrics and lowering memory and CPU footprint. This was achieved through a new design that allowed for better integration with Datadog's Cluster Check feature, leading to significant improvements in performance. The company also plans to introduce ways to register custom MetricFamilies for any Kubernetes resource and generate metrics for CRDs, allowing users to monitor custom resources more easily.
