Scripts written and used by NLANR

access-extract.pl

Generates a raw data summary of an access.log file. The output from this script is designed for further processing by access-summary.pl.

access-extract-urls.pl

Just like access-extract.pl, but it extracts the most popular URLs. It is a separate script because on-disk hash tables must be used.

access-summary.pl

Generates a tabular report of the logfile summary data.

cache-summary.pl

Generates a less-detailed report for multiple caches. Looks for summary files in a hard-coded directory.

squid-logs.pl

"library" routines needed by the other Perl scripts. Must be present in the same directory as the others.

TYPICAL USAGE:

	% access-extract.pl < access.log > summary
	% access-extract-urls.pl < access.log >> summary
	% access-summary.pl < summary > report.txt

NOTE: If you have 'emulate_httpd_log on', then you'll need to use the -h option to access-extract.pl.
