Annotations, Change, Context, Cover, Directory
Learn to analyze software traces and logs by exploring key patterns like message annotations, changes, context, cover, and directory. This lesson helps you understand how to track message evolution, organize log data, and apply complex analysis techniques for improved problem diagnosis in software environments.
We'll cover the following...
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:
