Telemetry Logs
Raw, unprocessed data streams recorded by sensors or instruments, showing measurements and events exactly as captured—before any human analysis or editing.

Unprocessed digital records automatically generated by sensors, instruments, or systems that document measurements, events, and system performance in real time. Telemetry logs preserve the original data exactly as captured, without interpretation, curation, or editing, making them valuable for independent analysis and verification.
What this means in real life
When a fitness tracker records your heart rate every second throughout a workout, those raw measurements form a telemetry log—before the app summarizes it as 'average 120 bpm.' A researcher could examine the original log to spot patterns the app's summary missed.
What it isn’t
Not a summary, report, or analyst's interpretation of data. A telemetry log is the raw numbers themselves, not someone's conclusion about what those numbers mean.
Commonly misused online
Often conflated with 'metadata' or 'logs' in general; people sometimes use it to mean any recorded information, when it specifically refers to sensor-generated measurement data captured automatically without human filtering.
