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. In Linguistics, conversion, also called zero derivation, is a kind of Word formation; specifically it is the creation of a Word A Logbook was originally a book for recording readings from the log, and is used to determine the distance a ship traveled within a certain amount of time Events and trends Nationalistic independence helped reshape the world during this decade Greece gains independence from the Ottoman Empire 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. Year 1963 ( MCMLXIII) was a Common year starting on Tuesday (link will display full calendar of the Gregorian calendar.

Computer data logging

Main article: Computer data logging

In computerized data logging, a computer program may automatically record events in a certain scope in order to provide an audit trail that can be used to diagnose problems. Computerized data logging is the process of recording events with an automated computer program in a certain scope in order to provide an audit trail that can be used to understand the activity Computer programs (also software programs, or just programs) are instructions for a Computer. An audit trail or audit log is a chronological sequence of audit records each of which contains evidence directly pertaining to and resulting from the execution of a business process or

Examples of physical systems which have logging subsystems include process control systems, and the black box recorders installed in aircraft. Process control is a Statistics and Engineering discipline that deals with Architectures mechanisms and Algorithms for controlling The flight data recorder ( FDR) or Black Box is a Flight recorder used to record specific Aircraft performance parameters

Many operating systems and multitudinous computer programs include some form of logging subsystem. An operating system (commonly abbreviated OS and O/S) is the software component of a Computer system that is responsible for the management and coordination Some operating systems provide a syslog service (described in RFC 3164), which allows the filtering and recording of log messages to be performed by a separate dedicated subsystem, rather than placing the onus on each application to provide its own ad hoc logging system. syslog is a standard for forwarding log messages in an IP network. Ad hoc is a Latin phrase which means "for this [ Purpose ]"

In many cases, the logs are esoteric and hard to understand; they need to be subjected to log analysis in order to make sense of them. Log analysis (or system and network log analysis) is an art and science seeking to make sense out of computer-generated records (also called log or Audit trail records


data logging is highly valuable to the scientific and general community

Automotive data logging

In automotive all DTC(Diagnostic Trouble Codes) are logged in ECUs(Engine Control Units) so that at the time of service of vehicle, service engineer will read all the DTCs by Tech-II or similar tools and will come to know problems occurred in Vehicle.
