Claim One:
1. A method for network path performance management, comprising: modeling a network path, including start and end nodes and a plurality of path segments of the network path, as a common set of objects and relationships between the objects; receiving a plurality of specific symptom alerts in response to state transitions of the objects; determining a limited problem domain based on the specific symptom alerts and the plurality of path segments that are modeled with weighted attributes indicative of at least one of: drop rate, error rate, incoming packet rate and outgoing packet rate, wherein the limited problem domain is less than an entire system repository of alerts; generating a specific codebook based on the limited problem domain; measuring at least one path performance characteristic for the modeled network path and at least one segment performance characteristic for each of the modeled plurality of path segments; determining causality information based on the performance characteristics measured for the modeled network path and each of the modeled plurality of path segments; and correlating the causality information using the specific codebook to identify at least one network path performance problem.
