1. A method of identifying a sequence of transmissions corresponding to a target transaction for embodiment on a network analysis system, comprising: identifying a reference transaction corresponding to the target transaction that includes a sequence of reference transmissions from multiple nodes in a plurality of tiers in a reference environment, collecting traffic information corresponding to a period of time within which the target transaction occurs, the traffic information including a plurality of production transmissions from multiple nodes in a plurality of tiers in a production environment, comparing the sequence of reference transmissions to the plurality of production transmissions to identify corresponding transmissions that form the sequence of transmissions corresponding to the target transaction, wherein comparing the sequence of reference transmissions to the plurality of production transmissions includes comparing an order of communications among tiers of a plurality of tiers in the reference environment with a corresponding order of communications among tiers of a plurality of tiers in the production environment, wherein said comparing involves eliminating at least a portion of the communications among tiers of a plurality of tiers in the production environment that are unrelated to the target transaction.
