# Kubernetes StatefulSets

The Kubernetes StatefulSets table provides information about Kubernetes StatefulSets monitored by Datadog across your clusters. Each row represents a Kubernetes StatefulSet and includes metadata about annotations, labels, replica counts (desired, ready, current, updated), pod management policy (OrderedReady, Parallel), update strategy (RollingUpdate, OnDelete), partition for partitioned rolling updates, governing headless service, status conditions, container and init container specs, selectors, resource requirements, and lifecycle timestamps. This table enables you to monitor StatefulSet health and rollout status, track replica availability, compare desired vs actual to detect issues, analyze update strategies and pod management policies, and correlate StatefulSets with pod and container performance. You can filter and view resources by kube_stateful_set tag in Datadog.
