Simple Log Service:Native plug-in: Apache mode parsing

Apache servers output logs based on the log format, log file path, and name specified in the Apache log configuration file. For example, the configuration CustomLog "/var/log/apache2/access_log" combined specifies that the combined format is used to print logs and that the log file path is /var/log/apache2/access_log.

• Apache log formats:

  • Combined format

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

  • Common format

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

  • Custom format

    LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\" %D %f %k %p %q %R %T %I %O" customized

  The following table describes the fields. For more information, see mod_log_config.
