Illustrative engineering notes for example purposes only.
Logs fail when they are either sparse (no context) or chatty (signal drowned in noise). A little structure up front saves hours during an incident.
Carry these on every entry
- Correlation id across requests and background jobs.
- Actor (user id, service name, or job type) at a stable cardinality.
- Outcome in plain language: succeeded, retried, failed validation, and so on.
Review a random hour of logs each sprint. If you cannot reconstruct a story, add one field—not ten.
