A lot of notifications relating to the status change are expected to generate in a node, especially when a network failure occurs and might cause a performance degradation of the node itself. To avoid such a defect, this object provides the maximum number of notifications generated per minute. If events occur more rapidly, the implementation may simply fail to emit these notifications during that period, or may queue them until an appropriate time. A value of 0 means no throttling is applied and events may be notified at the rate at which they occur.
