Annotations, Change, Context, Cover, Directory

This lesson introduces the following analysis patterns: Message Annotations, Message Change, Message Context, Message Cover, and Message Directory.

Message annotations

Message annotations analysis pattern was on our list for years, so it’s time to add it to the trace and log analysis pattern catalog. We also allow several annotations per trace message done at different times and annotations of different parts depending on the analysis flow (the topic of the next analysis pattern). When attached to log messages, annotations form their 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:
