At first I assumed this was similar to trace IDs, but it’s solving a different problem.
This is more like giving stable IDs to individual log statements (e.g. “upload started”, “upload retrying”, “upload failed”, “upload completed”), so you can see higher-level trends.
It makes it easy to see whether failures dropped after releasing a fix, without relying on fragile text searches.
Useful for team leads or engineering managers who want a high-level view of how system behavior changes over time.
