Configuring Cluster Monitoring Parameters

When the cluconfig utility is run to configure the cluster, it will prompt for configuration information which relates to operation of the Cluster Manager GUI.

The first GUI related parameter asks whether or not to configure a cluster alias. For example:

Enter IP address for cluster alias [NONE]: 172.16.33.128

A cluster alias consists of a floating IP address which will be active on either of the cluster members. For the purposes of this example, the IP is set to 172.16.33.128. It is useful to use this IP address (or associated hostname) within the browser when pointing it at the cluster member to monitor. If electing not to configure a cluster alias, then it is required to designate individual cluster members in order to monitor the cluster status using the GUI. The benefit of specifying the cluster alias is that the GUI will continue to be responsive as long as at least one cluster member is active.

The second GUI related parameter prompted for in cluconfig asks whether or not to allow remote monitoring. For example:

Do you wish to enable monitoring, both locally and remotely, via \
	  the Cluster GUI? yes/no [yes]:

Answering no disables Cluster GUI access completely.
