This is the job of a monitoring system. The monitoring system checks the state of the cluster form time to time and sends out notifications if anything is not as expected. You cannoy rely only on a cluster-centric solution. If all nodes are down, your users will notice. If you have a good monitoring system, it will recognize first and alert you. So you need external monitoring. I prefer SNMP since it is the only IETF standard in management protocols.
