# Kubernetes Clusters

The Kubernetes Clusters table provides comprehensive information about Kubernetes clusters monitored by Datadog. Each row represents a Kubernetes cluster and includes metadata about API server versions, kubelet versions running across nodes, total resource capacity and allocatable resources (CPU, memory, pods), node counts, and creation timestamps. This table enables you to get a high-level overview of your Kubernetes infrastructure, track cluster resource allocation and utilization, monitor version distribution across control plane and worker nodes, ensure cluster capacity meets demand, and correlate cluster-level metrics with workload performance. Datadog supports monitoring for all major Kubernetes distributions including AWS EKS, Azure AKS, Google GKE, Red Hat OpenShift, Rancher, and Oracle OKE.
