A network management apparatus and method processes network management data received during the monitoring of a network and generates events for presentation in an event list to a user when certain event conditions are detected. Network management data received in relation to an event condition is processed to determine whether it represents a recurring event condition. A recurring event condition is determined if a predetermined number of equivalent events have been generated, and appear in the event list, in an immediately preceding time period. In the described embodiment, if a recurring event condition occurs, a recurring event is generated, and subsequent occurrences of the event condition are not included in the event list presented to the user.
