# You need logtail (https://www.fourmilab.ch/webtools/logtail/)
#
# Your nginx configuration should look like this (i.e. $request_length $body_bytes_sent at the end):
# log_format main '$remote_addr - $remote_user $time_local "$request" '
# '$status $body_bytes_sent "$http_referer" '
# '"$http_user_agent" $request_length $body_bytes_sent';
#
# Log can be gathered from multiple sources by simply specifying multiple log filename
# and/or a log filename and a regex.
# - 'prod' => [ {'path' => '/home/prod/log/access.log'} ],
# Prod graph will be using everything in /home/prod/log/access.log
# - 'test' => [ {'path' => '/var/log/access.log', 'regex' => '"[A-Z]+ /test/'},
# {'path' => '/home/test/log/access.log'} ],
# Test graph will be using everything in /home/test/log/access.log and stuff that match
# '"[A-Z] /test/' in /var/log/access.log such as '"GET /test/'
