# Kubernetes Nodes

The Kubernetes Nodes table provides comprehensive information about Kubernetes nodes (worker machines) monitored by Datadog across your clusters. Each row represents a Kubernetes node and includes metadata about annotations, labels, resource capacity and allocatable resources (CPU, memory, pods), pod CIDR blocks for networking (including dual-stack support), cloud provider ID, taints that affect pod scheduling, node conditions (Ready, DiskPressure, MemoryPressure), cached container images, unschedulable status (cordoned nodes), and current phase. This table enables you to monitor node health and availability, track node resource capacity and allocation, identify resource pressure conditions, analyze pod scheduling constraints via taints and tolerations, correlate nodes with cloud provider instances, monitor node status for capacity planning, and troubleshoot pod scheduling issues. Kube-state-metrics provides detailed metrics on node status and capacity that Datadog collects for comprehensive node monitoring.
