Trace Analysis Patterns (Part 117)

Typical software trace may contain several Error Messages with different error codes and different exception names with Exception Stack Traces. Searching for individual codes or exceptions in problem databases may show many matches. Searching for all of them may show nothing. Therefore, we can construct the set of all subsets from the set of codes and exceptions (a power set) and perform analytic reasoning (and a search) based on certain subsets based on the problem description, Trace Viewpoints such as Use Case Trails, Motifs, Focus of Tracing, Foreground Components, (Adjoint) Threads of Activity, and simply some Activity Regions and Message Sets.

The following picture illustrates Error Powerset analysis pattern with a trace that has 4 error messages where 2 messages have the same error code.
