They are shown in the HW/SW invenotry and on the host detail page of the hosts. You can add the labels to other views and use the labels to filter your views. The labels will be used in more upcoming features in the future. - The check k8s_resouces is now used for Pods as well. - The new summary check k8s_pod_container for the Pods of a container is added. - The new inventory plugin k8s_pod_info shows Pod information in the HW/SW inventory. - The new check k8s_replicas monitors the replica sets of Deployments. - The new inventory plugin k8s_service_info shows information about Kubernetes Services. - The new inventory plugin k8s_selector shows the selectors of Kubernetes Services. - The new check k8s_service_port monitors the Ports defined for Kubernetes Services.
