Hi,

I am planning to include some `WatcherClient`s 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](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) ?

Regards  
Muthu

I would recommend upgrading to the latest version as that includes security features in the free basic license. Watcher however requires a commercial license irrespective of which client you are using.

Thanks for a quick reply Christian. Yes, we are already planning to move to 7.3.
