Common Log Format

From Wikipedia, the free encyclopedia

The Common Log Format is a standardised text file format used by web servers when generating log files. Because the format is standardised, the files may be analysed by a variety of analysis programs.

Each line in a file stored in the Common Log Format has the following syntax:

host ident authuser date request status bytes
