Clusters is a group of independent computers that work together to increase the availability of application and services. Cluster servers are also known as nodes. If one node happens to fail the other will set in to continue with the provision of service. This action is what is known as failover. The best way to monitor clusters is by trying to create a rule that will quickly pick up the event from the cluster nodes. For the Red hat cluster you need to have entitlement for the software for you to be able to install and configure. You use configuring tools to specify the relation among the clusters.
