1. A method comprising: collecting a plurality of trace files from a plurality of nodes involved in communicating data packets between one or more client devices and one or more data servers, wherein individual ones of the plurality of trace files includes trace entries and at least two trace files of the plurality of trace files are respectively collected from at least two layers of a same node of the plurality of nodes for which communication functions are characterized by an Open Systems Interconnection (OSI) model or an Internet Protocol (IP) suite; correlating the trace entries across the plurality of trace files; performing, via one or more processors configured with executable instructions, a communications analysis on the correlated trace entries to determine one or more of the plurality of nodes causing a problem that degrades a level of data service; and reporting the problem degrading the level of data service and the one or more nodes causing the problem degrading the level of data service.
