In a network management system, a main processor is connected to nodes of a network to receive alarm messages therefrom and to transmit command messages thereto. Unique relationships between alarm messages and network events are defined in a map. Received messages are sorted according to the map, so that those of the messages defined in the map are detected and supplied to an auxiliary processor. The auxiliary processor has a procedure registration table for storing procedures addressable with an event identifier supplied from the map. Each procedure specifies recovery actions to be taken by the network and a count threshold value. A manual event entry means is provided for defining the map and entering procedures into the procedure registration table. A message counter is responsive to a procedure supplied from the procedure registration table for counting the alarm messages supplied from the main processor for producing an output when the count threshold specified by the procedure is reached. An analyzer, receives the alarm messages from the main processor and is responsive to the output of the message counter for analyzing the alarm messages which have been received during the count period. From the output of the analyzer command messages are generated and transmitted to the network.
