Fig. shows codebook correlation. Monitors capture alarm events & input then to the correlator. The configuration model contains the configuration of the network.

The event model represents various events and their casual relationships. The correlator correlated the alarm events with the event model and determines the common problems that caused the alarm event, In this approach, problem events are viewed as messages generated by a system and encoded in sets of alarms that they cause. The function of correlator is to decode those problem messages to identify problems, this coding techniques comprised two phase
1. Code book selection phase 2. Correlator

To generate the code book matrix of problem system, first consider a causality graph, Each node in graph represents an event
