A platform team wants log data that downstream systems can reliably parse and analyze at scale. Which log format should it prefer in production?

Question

Accepted Answer

A. Structured logs with a stable schema. The OpenTelemetry logs documentation recommends structured logs in production because a stable schema makes them easier to validate, parse, correlate, and analyze at scale. Structured data reduces the amount of custom parsing needed downstream. Option b is wrong because unstructured logs are harder to parse consistently and usually require extra preprocessing.
