    HttpLog模块

    ngx_http_log_module实例

    1. log_format  gzip  '$remote_addr - $remote_user [$time_local]  '
    2. : '"$request" $status $bytes_sent '
    3. : '"$http_referer" "$http_user_agent" "$gzip_ratio"';
    4. access_log  /spool/logs/nginx-access.log  gzip  buffer=32k;

    指令

    • access_log
    • log_format

      access_log

    语法：*accesslog 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:

    • $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
    • $timelocal, local time into common log format.
      The headers, transmitted to client, begin from the prefix "sent_http      ", for example, $sent_http_content_range.

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

    1. log_format  combined  '$remote_addr - $remote_user [$time_local]  '
    2. : '"$request" $status $apache_bytes_sent '
    3. : '"$http_referer" "$http_user_agent"';
