Trace Analysis Patterns (Part 93)

Sometimes we have several use case instances traced in one log file. Messages and Activity Regions from many Use Case Trails intermingle and make analysis difficult especially with the absence of UCID (Use Case ID), any other identification tags, or Message Links. However, initially most of the time we are interested in a sequence of Significant Events. After finding Anchor Messages we can use Time Deltas to differentiate between trace statements from different Use Case Trails. Here we assume correct Event Sequence Order. We call this pattern Event Sequence Phase by analogy with wave phases (all such individual “waves” may have different “shapes” due to various delays between different stages of their use case and implementation narratives):

In the picture above we also identified Dominant Event Sequence for use case instance C.
