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. 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
