In [[computing]], '''logging''' is the act of keeping a [[wikt:log#Etymology 2|log]] of [[Event (computing)|events]] that occur in a computer system, such as problems, errors or justbroad information on current operations. These events may occur in the [[operating system]] or in other [[software]]. A message or ''log entry'' is recorded for each such event. These log messages can then be used to monitor and understand the operation of the system, to [[debugging|debug]] problems, or during an [[audit]]. Logging is particularly important in [[multi-user software]], to have a central overview of the operation of the system.

In the simplest case, messages are written to a file, called a ''log file''.<ref>{{cite web |url= https://blog.pandorafms.org/log-monitoring/ |title= Log Monitoring: not the ugly sister |access-date = February 14, 2018 |last= DeLaRosa |first= Alexander |date= February 8, 2018 |website= [[Pandora FMS]] |language = english |quote= A log file is a text file or XML file used to register the automatically produced and time-stamped documentation of events, behaviors and conditions relevant to a particular system. |archive-url= https://web.archive.org/web/20180214153657/https://blog.pandorafms.org/log-monitoring/

That can be used to understand the activity of the system and to diagnose problems.

They are essential to understand particularly in the case of applications with little user interaction.
