Abstract

A limited number of different types of event-processing node are provided for use as building blocks in constructing an event-processing system intended to receive and process event information about basic events occurring in a system being monitored, such as a telecommunications system. The event-processing system is constructed by interconnecting selected ones of the nodes into a network. Each event-processing node receives event data items in one or more input streams and processes these event data items to produce an output stream of event data items. Each event data item relates either to a basic event or to a combination of such events and includes event data that is indicative of the nature and time of occurrence thereof in the system being monitored. Generally, certain of the nodes effect processing on the basis of each input event data item taken individually, whilst other of the nodes are responsive to the presence of a predetermined inter-relationship between events represented by event data items.
