You can create a cluster in Halon under the Hosts -> Cluster page. To get started, click on the Setup clustering button and then enter the address (IP or FQDN) and login credentials for the node that you would like to join to the cluster. Also select if you want to use TLS and synchronize rates.
The cluster uses the HTTP(S) protocol to communicate with other nodes and rates are synchronized over a different port (UDP 13131).
Click on the Create button to create the cluster.
Also note when you add a node to a cluster, it will overwrite all configuration on that node.
Both the connectivity and configuration column should now say OK for the new node that joined the cluster.
You can now add more nodes to your cluster, please visit our Join a new node to the cluster article for more information.
