A complex system, e.g. a telecommunications network, is monitored for fault conditions. In order to correlate the alarms to establish which alarms (e.g. 31, 32, 33) have a common cause, a logical connectivity model is used in which a logical property is transferred between related logical elements (e.g. 41, 52) in response to the element (41) being alarmed. If as a result of such transfer the value of the logical property exceeds a threshold value for any element (61) a correlation is established and the element (61) highlighted (72) as the probable cause of the alarms. |
