D. The Causal Engine and NNMi Incidents
Communications and data networks have grown significantly in size and complexity, and so has the number of faults that occur. A single failure can trigger many alarms. Distinguishing real problems from anecdotal alarms has become a bottleneck for network operators. Traditional event correlation systems are able to reduce the number of alarms, but these systems tend to fall short in terms of identifying the root causes in an automated manner.
The NNMi Causal Engine technology applies root cause analysis (RCA) to network symptoms, using a causality-based approach to incident generation.
