Typically, a new logfile is created periodically, and the old logfile is renamed by appending a "1" to the name. Each time a new log file is started, the numbers in the file names of old logfiles are increased by one, so the files "rotate" through the numbers (thus the name "log rotation").
A log-structured filesystem is a file system in which data and metadata are written sequentially to a circular buffer, called a log.The design was first proposed in 1988 by John K. Ousterhout and Fred Douglis and first implemented in 1992 by Ousterhout and Mendel Rosenblum for the Unix-like Sprite distributed operating system.
Common Log File System (CLFS) is a general-purpose logging subsystem that is accessible to both kernel-mode as well as user-mode applications for building high-performance transaction logs. It was introduced with Windows Server 2003 R2 and included in later Windows operating systems.
Log management is the process for generating, transmitting, storing, accessing, and disposing of log data. A log data (or logs) is composed of entries (records), and each entry contains information related to a specific event that occur within an organization's computing assets, including physical and virtual platforms, networks, services, and cloud environments.
The following command will display the last 10 lines of messages and append new lines to the display as new lines are added to messages: tail -f /var/adm/messages To keep following the log even when it is recreated, renamed, or removed as part of log rotation, at least BSD and GNU implementations provide a -F option which is useful in cases ...
For computer log management, the Common Log Format, [1] also known as the NCSA Common log format, [2] (after NCSA HTTPd) is a standardized text file format used by web servers when generating server log files. [3]
A server log is a log file (or several files) automatically created and maintained by a server consisting of a list of activities it performed. A typical example is a web server log which maintains a history of page requests. The W3C maintains a standard format (the Common Log Format) for web server log files, but other proprietary formats ...
