|
#
|
|
# 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 graph will be using everything in /home/prod/log/access.log
