SNMP Trap: Cluster Status
-------------------------

A trap is generated when one or more nodes are down in a cluster.

Identification

* The originating IP / hostname is used to identify the system generating the traps
* The NMS is responsible for associating traps with each managed system, along with clearing of alarms and escalation to the relevant system operator
* The trap OID is generic  for various SNMP events monitored by the system
* The SNMP system name is included as part of the variable binding to assist identification: 
* .iso.org.dod.internet.mgmt.mib-2.system.sysName.0 = standalone
