Threshold notification
Once a threshold meets or reaches a limit, the Launcher sends a notification message to the SNMP Agent, who then issues a trap to the SNMP manager.
While the threshold count is still equal or above the limits, no more messages will be sent for that threshold until the count falls below the limit. A flag is reset at this time, and notifications are sent the next time the limit is reached.
Threshold notification method
The type of notification method used by the SNMP Agent is called single edge. Single edge notification occurs when a value exceeds the threshold limit and the LowerBound and UpperBound values, the upper or lower limit in a permitted range of values, are the same.
