Abstract: A system for analyzing communication network events on a historical basis based on records received from the network. A data processing system is connected via a first communications co-processor to a node of the network, permitting access to the node processor event log. In response to an inquiry sent from the data processing system, the events are collected as they are reported to the node processor. A record of the events is made in a table corresponding to the particular type of event received. The records in all tables may be sorted based on dates supplied by a system operator. The sorted records comprise a report identifying particular network elements which constituted an event during the reporting period.
