SQUID Frequently Asked Questions Squid Log Files


Most log file analysis program are based on the entries in access.log. Currently, there are two file formats possible for the log file, depending on your configuration for the emulate_httpd_log option. By default, Squid will log in its native log file format. If the above option is enabled, Squid will log in the common log file format as defined by the CERN web daemon.

The common log file format contains other information than the native log file, and less. The native format contains more information for the admin interested in cache evaluation.
