node through which the service is accessed is removed from the cluster or if it otherwise becomes unreachable. This will add a deployment for clustermesh-apiserver into your cluster, as well as the related namespaces like CAP_NET_ADMIN without affecting security since BPF enforcement points in the host are unreachable for the container. Given BPF programs are attached from the host’s network namespace, BPF also labeled by action type Cluster health Name Labels Description unreachable_nodes Number of nodes that cannot be reached unreachable_health_endpoints Number of health endpoints that cannot be reached
