Trace Analysis Patterns (Part 174)

Saturday, July 20th, 2019

Message Annotations analysis pattern was on our list for years so it’s time to add it to trace and log analysis pattern catalog. We also allow several annotations per trace message done at different times and annotating different parts depending on the analysis flow (the topic of the next analysis pattern). Attached to log messages annotations form their own Adjoint Thread of Activity. However, sorted by their annotation time or sequence we get a different trace that we call Annotation Trace (an example of analysis narrative). We can apply all relevant analysis patterns to both traces. A sketch of this pattern is depicted in the following diagram:
