If an OpenView event contains this var-bind, it indicates to the Event Correlation System the importance of the node from an event correlation perspective. In situations where the ECS system would normally suppress an event, it may choose not to suppress it if the node is very important (e.g. an important server node). The integral value of this MIB object may evolve over time. For now, non-integral values are invalid, a value of zero indicates that the node is a regular node and a non-zero value indicates that the node is an important node.
