Trace Analysis Patterns (Part 88)
Tuesday, June 24th, 2014The previous patterns such as Basic Facts and Vocabulary Index address the mapping of a problem description to software execution artefacts such traces and logs. Indirect Facts analysis pattern addresses the problem of an incomplete problem description. However, we need another pattern for completeness that addresses the mapping from a log to troubleshooting and debugging recommendations. We call it Hidden Facts which are uncovered by trace analysis. Of course, there can be many such hidden facts and usually they are uncovered after narrowing down analysis to particular Threads of Activity, Adjoint Threads, Message Context, Message Set, or Data Flow. The need for that pattern had arisen during the pattern-oriented analysis of the trace case study from Malcolm McCaffery and can be illustrated on this diagram:
