Logging (computing) In computing, logging is the act of keeping a log of events that occur in a computer system, such as problems, errors or just 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.
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] Because the format is standardized, the files can be readily analyzed by a variety of web analysis programs, for example Webalizer ...
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. [ 1]
Log analysis. In computer log management and intelligence, log analysis (or system and network log analysis) is an art and science seeking to make sense of computer-generated records (also called log or audit trail records). The process of creating such records is called data logging . Typical reasons why people perform log analysis are:
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.
Syslog. In computing, syslog / ˈsɪslɒɡ / is a standard for message logging. It allows separation of the software that generates messages, the system that stores them, and the software that reports and analyzes them. Each message is labeled with a facility code, indicating the type of system generating the message, and is assigned a severity ...
Event Viewer is a component of Microsoft 's Windows NT operating system that lets administrators and users view the event logs, typically file extensions .evt and .evtx, on a local or remote machine. Applications and operating-system components can use this centralized log service to report events that have taken place, such as a failure to ...
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. CLFS can be used for both data logging as well as for event ...
