Trace Analysis Patterns (Part 225)

Saturday, February 18th, 2023

Trace Nerve is Thread of Activity or Adjoint Thread of Activity that runs through all Activity Regions. An example is illustrated in the following diagram:

Of course, depending on trace or log, there can be several Trace Nerves. This analysis pattern was inspired by nerve complexes in topology.

Trace Analysis Patterns (Part 224)

Saturday, February 18th, 2023

Looking at software traces and logs as 2-categories allows us to consider Whisker Traces (horizontal composition) in addition to vertical composition such as Serial Traces, Trace Mask, and Container Traces. The same ATIDs can be combined, and if there is a time mismatch, additional message copies need to be added (whiskering). The process is illustrated in the following diagram:
