Extended Log Format
Extended Log Format (ELF) is a standardized text file format that is used by web servers when generating log files. In comparison to the Common Log Format (CLF), ELF provides more information and flexibility. Example #Version: 1.0 #Date: 12-Jan-1996 00:00:00 #Fields: time cs-method cs-uri 00:34:23 GET /foo/bar.html 12:21:16 GET /foo/bar.html 12:45:52 GET /foo/bar.html 12:57:34 GET /foo/bar.html See also * Common Log Format Sources Extended Log File Format*as described in the documentation of the World Wide Web consortia webserver ( W3C httpd).

Server Log
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. These log messages can then be used to monitor and understand the operation of the system, to 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. Alternatively, the messages may be written to a dedicated logging system or to a log management software, where it is stored in a database or on a different computer system. Specifically, a transaction log is a log of the communications between a system and the users of that system, or a data collection method that automatically captures the type, content, or time of transactions ...

Common Log Format
For computer log management, the Common Log Format, also known as the NCSA Common log format, (after NCSA HTTPd) is a standardized text file format used by web servers when generating server log files. Because the format is standardized, the files can be readily analyzed by a variety of web analysis programs, for example Webalizer and Analog. Each line in a file stored in the Common Log Format has the following syntax: host ident authuser date request status bytes The format is extended by the Combined Log Format with referer and user-agent fields. Example 127.0.0.1 user-identifier frank 0/Oct/2000:13:55:36 -0700"GET /apache_pb.gif HTTP/1.0" 200 2326 A dash () in a field indicates missing data. * is the IP address of the client (remote host) which made the request to the server. * is the RFC 1413 identity of the client. Usually "-". * is the userid of the person requesting the document. Usually "-" unless .htaccess has requested authentication. * is the date, t ...

Computer File Formats
A computer is a machine that can be programmed to carry out sequences of arithmetic or logical operations ( computation) automatically. Modern digital electronic computers can perform generic sets of operations known as programs. These programs enable computers to perform a wide range of tasks. A computer system is a nominally complete computer that includes the hardware, operating system (main software), and peripheral equipment needed and used for full operation. This term may also refer to a group of computers that are linked and function together, such as a computer network or computer cluster. A broad range of industrial and consumer products use computers as control systems. Simple special-purpose devices like microwave ovens and remote controls are included, as are factory devices like industrial robots and computer-aided design, as well as general-purpose devices like personal computers and mobile devices like smartphones. Computers power the Internet, which links ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
