1. A method of analyzing network traffic comprising:
- selecting a primary metric from a plurality of collected metrics associated with network element metrics and/or node-to-node contexts;
generating correlation coefficients between the primary metric and ones of at least a portion of the plurality of collected metrics; and
generating a hypothesis set based on the correlation coefficients,wherein at least one of selecting a primary metric, generating correlation coefficients, and generating a hypothesis set is performed using at least one processor.

Abstract
Provided are methods and computer program products for monitoring the contents of network traffic in a network device and performing correlation analysis of collected performance metrics to help identify reasons for network performance issues. Methods for correlation analysis include selecting scope and network metric types to include in the correlation analysis to generate an educated candidate set for correlation analysis. The correlation analysis methods result in a hypothesis set that assist the operator in identifying transactions and infrastructure problems resulting in network performance degradation.
