Data logging

Data logging is the practice of recording sequential data, often chronologically.

Etymology

"To log" is a verb derivative of the noun "logbook"; the verb form means "to record in a logbook", and may have been coined in the 1820s. The term "logbook" itself stems from the practice of floating a stationary "log" (actually a wooden block attached to a reel via rope) to provide a fixed point of reference for the purpose of measuring a ship's speed (see "Knot (speed)"). Computer scientists adopted the verb "to log" circa 1963 to describe the systematic recording of specific types of data processing events.

Automotive data logging

In automobiles, all diagnostic trouble codes (DTCs) are logged in engine control units (ECUs) so that at the time of service of a vehicle, a service engineer will read all the DTCs using Tech-II or similar tools and will come to know problems occurred in the vehicle.
