The node controller checks the state of each node every `--node-monitor-period` seconds. In versions of Kubernetes prior to 1.13, NodeStatus is the heartbeat from the -node. Starting from Kubernetes 1.13, node lease feature is introduced as an -alpha feature (feature gate `NodeLease`, -[KEP-0009](https://github.com/kubernetes/enhancements/blob/master/keps/sig-node/0009-node-heartbeat.md)). +node. Node lease feature is enabled by default since 1.14 as a beta feature +(feature gate `NodeLease`, [KEP-0009](https://github.com/kubernetes/enhancements/blob/master/keps/sig-node/0009-node-heartbeat.md)). When node lease feature is enabled, each node has an associated `Lease` object in `kube-node-lease` namespace that is renewed by the node periodically, and both NodeStatus and node lease are treated as heartbeats from the node.
