It is worth noting that the low flap threshold should be lower than the high flap threshold. This prevents the situation where, after one state transition, flapping would be detected, and the next check would tell Nagios that the object has stopped flapping. If both the attributes are set to the same value, an object might be identified as having started and stopped flapping often. This can happen when the flapping threshold changes from below threshold to above threshold or vice versa. This might cause Nagios to send out a large number of notifications and cause its performance to degrade.
