People who run AWStats on large log files have most likely noticed: the data
|
|
files can grow quite large, resulting in both a waste of disk space and longer
|
|
page generation times for the AWStats pages. I wrote a small script that
|
|
analyzes these data files and can remove any information you think is
|
|
unnecessary.
|
|
|
|
B<Download:> L<awshrink|http://dev.yorhel.nl/download/code/awshrink> (copy to
|
|
/usr/bin to install).
|
|
|
|
|
|
=head2 Important
|
|
|
|
Do B<NOT> use this script on data files that are not completed yet (i.e. data
|
|
files of the month you're living in). This will result in inaccurate sorting of
|
|
visits, pages, referers and whatever other list you're shrinking. Also, keep
|
|
in mind that this is just a fast written perl hack, it is by no means fast and
|
|
may hog some memory while shrinking data files.
|
|
|
|
|
|
=head2 Usage
|
|
|
|
awshrink [-c -s] [-SECTION LINES] [..] datafile
|
|
-s Show statistics
|
|
-c Overwrite datafile instead of writing to a backupfile (datafile~)
|
|
-SECTION LINES
|
|
Shrink the selected SECTION to LINES lines. (See example below)|;
|
|
|
|
|
|
=head2 Typical command-line usage
|
|
|
|
While awshrink is most useful for monthly cron jobs, here's an example of basic
|
|
command line usage to demonstrate what the script can do:
|
|
|
|
$ wc -c awstats122007.a.txt
|
|
29916817 awstats122007.a.txt
|
|
