Modifying OpsCenter cluster connections

Cluster Connections settings define how OpsCenter connects to a cluster. Edit the settings if you have enabled authentication or encryption on a cluster.

The connections settings for a cluster define how OpsCenter connects to a cluster. For example, if you’ve enabled authentication or encryption on a cluster, you’ll need to specify that information in the cluster connections settings.

  2. Click Settings > Cluster Connections.
    The Edit Cluster dialog appears.
  3. Change the IP addresses of cluster nodes if applicable.
  4. Change JMX and Thrift listen port numbers if applicable.
  5. Edit the user credentials if the JMX or Thrift ports require authentication.
