# Perl script to monitor total bandwidth *byprojects* (e.g. vhost) from multiple files and/or regex.

#
# You need logtail (https://www.fourmilab.ch/webtools/logtail/) and
#
# mod_logio apache module (https://httpd.apache.org/docs/2.0/mod/mod_logio.html).
# Your logformat should look like this "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\" %I %O"
# where %I is input and %O is output.
#
# Log can be gather from multiple sources by simply specifying multiple log filename and/or an array with two
# elements: log filename and a regex.
# - 'prod' => array('/home/prod/log/access.log'),
# Prod graph will be using everything in /home/prod/log/access.log
# - 'test' => array(array('/var/log/httpd/access.log', '"[A-Z]+ /test/'), '/home/test/log/access.log')
# Test graph will be using eveything in /home/test/log/access.log and stuff that match '"[A-Z] /test/' in
# /var/log/httpd/access.log such as '"GET /test/'
$statepath = '/usr/local/var/munin/plugin-state'; # directory where logtail will save the state
$logtail = '/usr/local/bin/logtail';

'test' => (
('/var/log/httpd/access.log', '"[A-Z]+ /test/'),
