 * access_log
 * log_format

= access_log = 语法： access_log path [format [buffer=size | off ] 默认值： access_log log/access.log combined

作用域： http, server, location

指令 access_log 指派路径、格式和缓存大小. 参数 "off" 将清除当前级别的所有 access_log 指令. 如果未指定格式，则使用预置的 "combined" 格式. 缓存不能大于能写入磁盘的文件的最大大小. 在 FreeBSD 3.0-6.0 ，缓存大小无此限制.

= log_format = 语法： log_format name format [format ...] 

默认值： log_format combined "..."

作用域： http server

Directive log_format describes the format of a log entry. Besides general variables in the format it is possible to use variables which exist only at the moment of record into the log:

The headers, transmitted to client, begin from the prefix "sent_http_", for example, $sent_http_content_range.
 * $body_bytes_sent, the number of bytes, transmitted to client minus the response headers, variable is compatible with parameter %B of module Apache's mod_log_config (this was called $apache_bytes_sent, before version 0.3.10)
 * $bytes_sent, the number of bytes, transmitted to client
 * $connection, the number of connection
 * $msec, the time with an accuracy to microseconds at the moment of the log entry
 * $pipe, "p" if request was pipelining
 * $request_length, the length of the body of the request
 * $request_time, the time of working on request in seconds
 * $status, status of answer
 * $time_local, local time into common log format.

In the configuration there is always a predetermined format "combined":

log_format combined  '$remote_addr - $remote_user [$time_local]  '
 * '"$request" $status $apache_bytes_sent '
 * '"$http_referer" "$http_user_agent"';
