<IfModule log_config_module>

    #

    # The following directives define some format nicknames for use with

    # a CustomLog directive (see below).

    #

    LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined

    LogFormat "%l %h %u %t \"%r\" %>s %b" common

    <IfModule logio_module>

      # You need to enable mod_logio.c to use %I and %O

      LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\" %I %O" combinedio

    </IfModule>

    #

    # The location and format of the access logfile (Common Logfile Format).

    # If you do not define any access logfiles within a <VirtualHost>

    # container, they will be logged here.  Contrariwise, if you *do*

    # define per-<VirtualHost> access logfiles, transactions will be

    # logged therein and *not* in this file.

    #

    CustomLog "logs/access_log" common

    #

    # If you prefer a logfile with access, agent, and referer information

    # (Combined Logfile Format) you can use the following directive.

    #

    #CustomLog "logs/access_log" combined

위와 같이 CustomLog & LogFormat은 매칭으로 이루어져 있습니다.

LogFormat "log 포멧" nickname

CustomLog "log 경로" nickname

위와 같은 형태로 nickname 기준으로 LogFormat을 결정합니다.

마찬가지로 vhost & ssl에 설정된 CustomLog에서도 직접 LogFormat을 설정할수도 있으며, httpd.conf에 설정된 LogFormat의 nickname을 불러올 수도 있습니다.
