I had to scroll almost to the bottom to find it, but this is the right answer. We already had logs. We added "mapped diagnostic contexts" and standardized the emission format to make them into easy-to-analyze structured logs. Those were very useful. Then we had so many structured logs that storing, filtering and aggregating them became a bigger problem than just keeping the application running. So we split the structured logs into smaller structured logs, some of them with pre-filtering and pre-aggregation to keep the firehose of structured log spam manageable. Someone branded this new form of logging "observability" and here we are. Planning for the next big paradigm shift. Which apparently is... a stream of structured logs. Okay then.
