I am planning to include some
WatcherClients for our cluster for monitoring cluster-state to begin with. I am following the instructions provided here : https://www.elastic.co/guide/en/x-pack/current/api-java.html.
Our cluster is NOT x-pack enabled and as I understand this requires license. Hence , can
PreBuiltXPackTransportClient be used in any cluster or the servers need to be configured specifically with any x-pack modules (with suitable licenses if required) ?
