A GUI for a Network Management System client is provided. The GUI presents network alarms in more than one alarm window. Each alarm window includes a drop-down menu for selecting an alarm filter and a pause button for halting display of new alarms. Alarm filters may be retrieved from a database accessible from a number of NMS clients, thereby allowing public filters to be created by a supervisor. A method of automatically populating the 'additional text' field of alarms in a way specified manually after installation of the NMS, which provides additional means of filtering alarms. The invention provides an improved interface by which network administrators can manage network alarms, the interface being particularly advantageous during floods of large numbers of network alarms.

Multiple displays of large dynamic alarm windows

An alarm correlation method with rules and model is disclosed for suppression of alarms which will clear when another alarm clears. The alarm correlation method with rules and model includes a list of objects which alarms may be raised, and a list of correlation rules for each of the objects which associates objects which have correlated alarms, and a method of traversing the lists so that correlated alarms may be suppressed. The alarm correlation method with rules and model is particularly useful for overcoming operator overload due to the presence of multiple correlated alarms.
