Description: The counter of the output traps. It increases by one every time a new trap is sent to all the managers configured in the relevant table. In this way its value is the number of notification events occurred since the last agent reset and every manager that reads this value can understand whether some event has been lost or not. (Note that in general this counter differs from the RFC1213 snmpOutTraps, that counts the number of Trap PDUs sent). When the logging mechanism is enabled, it corresponds to the index in the eventlog table
