Logs are written in a customizable format, and may be - written directly to a file, or to an external program. - Conditional logging is provided so that individual requests may - be included or excluded from the logs based on characteristics - of the request.</p> - - <p>Three directives are provided by this module: - <code>TransferLog</code> to create a log file, - <code>LogFormat</code> to set a custom format, and - <code>CustomLog</code> to define a log file and format in one - step. The <code>TransferLog</code> and <code>CustomLog</code> - directives can be used multiple times in each server to cause - each request to be logged to multiple files.</p> -<h2>Directives</h2><ul><li><a href="#cookielog">CookieLog</a></li><li><a href="#customlog">CustomLog</a></li><li><a href="#logformat">LogFormat</a></li><li><a href="#transferlog">TransferLog</a></li></ul><p><strong>See also </strong></p><ul><li><a href="../logs.html">Apache Log Files</a></li></ul><h2><a name="formats">Custom Log Formats</a></h2> - - - <p>The format argument to the <code>LogFormat</code> and - <code>CustomLog</code> directives is a string. This string is - logged to the log file for each request. It can contain literal - characters copied into the log files and the c-type control - characters "\n" and "\t" to represent new-lines and tabs. - Literal quotes and back-slashes should be escaped with - back-slashes.</p> - - <p>The characteristics of the request itself are logged by - placing "%" directives in the format string, which are replaced - in the log file by the values as follows:</p> - -<table> - -<tr><td>%...a:</td> -<td>Remote IP-address</td></tr> - -<tr><td>%...A:</td> -<td>Local IP-address</td></tr> - -<tr><td>%...B:</td> -<td>Bytes sent, excluding HTTP headers.</td></tr> - -<tr><td>%...b:</td> -<td>Bytes sent, excluding HTTP headers.

The forms of condition are a list of - HTTP status codes, which may or may not be preceded by "!". - Thus, "%400,501{User-agent}i" logs User-agent: on 400 errors - and 501 errors (Bad Request, Not Implemented) only; - "%!200,304,302{Referer}i" logs Referer: on all requests which - did <strong>not</strong> return some sort of normal status.</p> - - <p>Note that there is no escaping performed on the strings from - %...r, %...i and %...o.

It can specify either a <em>nickname</em> defined by - a previous <a href="#logformat">LogFormat</a> directive, or it - can be an explicit <em>format</em> string as described in the - <a href="#formats">log formats</a> section.</p> - - <p>For example, the following two sets of directives have - exactly the same effect:</p> - -<blockquote><table cellpadding="10"><tr><td bgcolor="#eeeeee"><code> - # CustomLog with format nickname<br> - LogFormat "%h %l %u %t \"%r\" %>s %b" common<br> - CustomLog logs/access_log common<br> -<br> - # CustomLog with explicit format string<br> - CustomLog logs/access_log "%h %l %u %t \"%r\" %>s %b"<br> -</code></td></tr></table></blockquote> - - <p>The third argument is optional and allows the decision on - whether or not to log a particular request to be based on the - presence or absence of a particular variable in the server - environment. If the specified <a href="../env.html">environment - variable</a> is set for the request (or is not set, in the case - of a '<code>env=!<em>name</em></code>' clause), then the - request will be logged.</p> - - <p>Environment variables can be set on a <em>per</em>-request - basis using the <code><a href="mod_setenvif.html">mod_setenvif</a></code> - and/or <code><a href="mod_rewrite.html">mod_rewrite</a></code> modules. For - example, if you don't want to record requests for all GIF - images on your server in a separate logfile but not your main - log, you can use:</p> - -<blockquote><table cellpadding="10"><tr><td bgcolor="#eeeeee"><code> - SetEnvIf Request_URI \.gif$ gif-image<br> - CustomLog gif-requests.log common env=gif-image<br> - CustomLog nongif-requests.log common env=!gif-image -</code></td></tr></table></blockquote> -<hr/><h2><a name="LogFormat">LogFormat</a> <a name="logformat">Directive</a></h2><table cellpadding="1" cellspacing="0" border="0" bgcolor="#cccccc"><tr><td><table bgcolor="#ffffff"><tr><td><strong>Description: </strong></td><td>Describes a format for use in a log file</td></tr><tr><td><a href="directive-dict.html#Syntax" class="help">Syntax:</a></td><td>LogFormat - <em>format</em>|<em>nickname</em> [<em>nickname</em>]</td></tr><tr><td><a href="directive-dict.html#Context" class="help">Context:</a></td><td>server config, virtual -host</td></tr><tr><td><a href="directive-dict.html#Status" class="help">Status:</a></td><td>Base</td></tr><tr><td><a href="directive-dict.html#Module" class="help">Module:</a></td><td>mod_log_config</td></tr><tr><td align="left" valign="top"><a href="directive-dict.html#Compatibility" class="help">Compatibility:</a></td><td>Nickname only available in Apache 1.3 or later. -</td></tr></table></td></tr></table> - <p>This directive specifies the format of the access log - file.</p> - - <p>The <code class="directive">LogFormat</code> directive can take one of two - forms. In the first form, where only one argument is specified, - this directive sets the log format which will be used by logs - specified in subsequent <code class="directive">TransferLog</code> - directives. The single argument can specify an explicit - <em>format</em> as discussed in <a href="#formats">custom log - formats</a> section above. Alternatively, it can use a - <em>nickname</em> to refer to a log format defined in a - previous <code class="directive">LogFormat</code> directive as described - below.</p> - - <p>The second form of the <code class="directive">LogFormat</code> - directive associates an explicit <em>format</em> with a - <em>nickname</em>. This <em>nickname</em> can then be used in - subsequent <code class="directive">LogFormat</code> or - <code class="directive">CustomLog</code> directives rather than - repeating the entire format string. A - <code class="directive">LogFormat</code> - directive which defines a nickname <strong>does nothing - else</strong> -- that is, it <em>only</em> defines the - nickname, it doesn't actually apply the format and make it the - default. Therefore, it will not affect subsequent - <code class="directive">TransferLog</code> directives.</p> - - <p>For example:</p> - - <blockquote><table cellpadding="10"><tr><td bgcolor="#eeeeee"><code>LogFormat "%v %h %l %u %t \"%r\" %>s %b" - vhost_common</code></td></tr></table></blockquote> - -<hr/><h2><a name="TransferLog">TransferLog</a> <a name="transferlog">Directive</a></h2><table cellpadding="1" cellspacing="0" border="0" bgcolor="#cccccc"><tr><td><table bgcolor="#ffffff"><tr><td><strong>Description: </strong></td><td>Specifly location of a log file</td></tr><tr><td><a href="directive-dict.html#Syntax" class="help">Syntax:</a></td><td>TransferLog <em>file</em>|<em>pipe</em></td></tr><tr><td><a href="directive-dict.html#Context" class="help">Context:</a></td><td>server config, virtual -host</td></tr><tr><td><a href="directive-dict.html#Status" class="help">Status:</a></td><td>Base</td></tr><tr><td><a href="directive-dict.html#Module" class="help">Module:</a></td><td>mod_log_config</td></tr><tr><td align="left" valign="top"><a href="directive-dict.html#Compatibility" class="help">Compatibility:</a></td><td/></tr></table></td></tr></table> - - <p>This directive has exactly the same arguments and effect as - the <code class="directive">CustomLog</code> directive, with the - exception that it does not allow the log format to be specified - explicitly or for conditional logging of requests. Instead, the - log format is determined by the most recently specified - specified <code class="directive">LogFormat</code> directive (which - does not define a nickname). Common Log Format is used if no - other format has been specified.</p> - - <p>Example:</p> -<blockquote><table cellpadding="10"><tr><td bgcolor="#eeeeee"><code> - LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-agent}i\""<br> - TransferLog logs/access_log -</code></td></tr></table></blockquote> - -<hr/></blockquote><h3 align="center">Apache HTTP Server Version 2.0</h3><a href="./"><img src="../images/index.gif" alt="Index"/></a><a href="../"><img src="../images/home.gif" alt="Home"/></a></body></html>
