<p>The server error log, whose name and location is set by the
<code class="directive"><a href="./mod/core.html#errorlog">ErrorLog</a></code> directive, is the
what went wrong and how to fix it.</p>
<p>The error log is usually written to a file (typically
- <code>error_log</code> on unix systems and
- <code>error.log</code> on Windows and OS/2). On unix systems it
+ <code>error_log</code> on Unix systems and
+ <code>error.log</code> on Windows and OS/2). On Unix systems it
is also possible to have the server send errors to
<code>syslog</code> or <a href="#piped">pipe them to a
program</a>.</p>
- <p>The format of the error log is relatively free-form and
- descriptive. But there is certain information that is contained
- in most error log entries. For example, here is a typical
- message.</p>
+ <p>The format of the error log is defined by the <code class="directive"><a href="./mod/core.html#errorlogformat">ErrorLogFormat</a></code> directive, with which you
+ can customize what values are logged. A default is format defined
+ if you don't specify one. A typical log message follows:</p>
<div class="example"><p><code>
- [Wed Oct 11 14:32:52 2000] [error] [client 127.0.0.1]
- client denied by server configuration:
- /export/home/live/ap/htdocs/test
+ [Fri Sep 09 10:42:29.902022 2011] [core:error] [pid 35708:tid 4328636416]
+ [client 72.15.99.187] File does not exist: /usr/local/apache2/htdocs/favicon.ico
</code></p></div>
<p>The first item in the log entry is the date and time of the
- message. The second entry lists the severity of the error being
- reported. The <code class="directive"><a href="./mod/core.html#loglevel">LogLevel</a></code>
- directive is used to control the types of errors that are sent
- to the error log by restricting the severity level. The third
- entry gives the IP address of the client that generated the
- error. Beyond that is the message itself, which in this case
- indicates that the server has been configured to deny the
- client access. The server reports the file-system path (as
- opposed to the web path) of the requested document.</p>
+ message. The next is the module producing the message (core, in this
+ case) and the severity level of that message. This is followed by
+ the process ID and, if appropriate, the thread ID, of the process
+ that experienced the condition. Next, we have the client address
+ that made the request. And finally is the detailed error message,
+ which in this case indicates a request for a file that did not
+ exist.</p>
<p>A very wide variety of different messages can appear in the
error log. Most look similar to the example above. The error
information written to <code>stderr</code> by a CGI script will
be copied directly to the error log.</p>
- <p>It is not possible to customize the error log by adding or
- removing information. However, error log entries dealing with
- particular requests have corresponding entries in the <a href="#accesslog">access log</a>. For example, the above example
- entry corresponds to an access log entry with status code 403.
- Since it is possible to customize the access log, you can
- obtain more information about error conditions using that log
- file.</p>
+ <p>Putting a <code>%L</code> token in both the error log and the access
+ log will produce a log entry ID with which you can correlate the entry
+ in the error log with the entry in the access log. If
+ <code class="module"><a href="./mod/mod_unique_id.html">mod_unique_id</a></code> is loaded, its unique request ID will be
+ used as the log entry ID, too.</p>
<p>During testing, it is often useful to continuously monitor
- the error log for any problems. On unix systems, you can

accomplish this using:</p>

+
+
+ <p>The <code class="directive"><a href="./mod/core.html#loglevel">LogLevel</a></code> directive
+ allows you to specify a log severity level on a per-module basis. In
+ this way, if you are troubleshooting a problem with just one
+ particular module, you can turn up its logging volume without also
+ getting the details of other modules that you're not interested in.
+ This is particularly useful for modules such as
+ <code class="module"><a href="./mod/mod_proxy.html">mod_proxy</a></code> or <code class="module"><a href="./mod/mod_rewrite.html">mod_rewrite</a></code> where you

+
<p>This format is exactly the same as the Common Log Format,
with the addition of two more fields. Each of the additional
<p>Multiple access logs can be created simply by specifying
- multiple <code class="directive"><a href="./mod/mod_log_config.html#customlog">CustomLog</a></code>
+ multiple <code class="directive"><a href="./mod/mod_log_config.html#customlog">CustomLog</a></code>
directives in the configuration
file. For example, the following directives will create three
access logs. The first contains the basic CLF information,
information. The last two <code class="directive"><a href="./mod/mod_log_config.html#customlog">CustomLog</a></code> lines show how
to mimic the effects of the <code>ReferLog</code> and <code>AgentLog</code> directives.</p>
- <div class="example"><p><code>
- LogFormat "%h %l %u %t \"%r\" %>s %b" common<br />
- CustomLog logs/access_log common<br />
- CustomLog logs/referer_log "%{Referer}i -> %U"<br />
- CustomLog logs/agent_log "%{User-agent}i"
- </code></p></div>
+ <pre class="prettyprint lang-config">LogFormat "%h %l %u %t \"%r\" %>s %b" common
+CustomLog logs/access_log common
+CustomLog logs/referer_log "%{Referer}i -> %U"
+CustomLog logs/agent_log "%{User-agent}i"</pre>
+
<p>This example also shows that it is not necessary to define a
nickname with the <code class="directive"><a href="./mod/mod_log_config.html#logformat">LogFormat</a></code> directive. Instead,

- include or exclude requests where the environment variable is
- set. Some examples:</p>

- SetEnvIf Request_URI "^/robots\.txt$" dontlog<br />
- # Log what remains<br />
- CustomLog logs/access_log common env=!dontlog
- </code></p></div>
<p>As another example, consider logging requests from
english-speakers to one log file, and non-english speakers to a
different log file.</p>
- <div class="example"><p><code>
- SetEnvIf Accept-Language "en" english<br />
+ <pre class="prettyprint lang-config"> SetEnvIf Accept-Language "en" english<br />
CustomLog logs/english_log common env=english<br />
- CustomLog logs/non_english_log common env=!english
- </code></p></div>
+ CustomLog logs/non_english_log common env=!english</pre>
+
+
+ <p>In a caching scenario one would want to know about
+ the efficiency of the cache. A very simple method to
+ find this out would be:</p>
+
+ <pre class="prettyprint lang-config">SetEnv CACHE_MISS 1
+LogFormat "%h %l %u %t "%r " %>s %b %{CACHE_MISS}e" common-cache
+CustomLog logs/access_log common-cache</pre>
+
+
+ <p><code class="module"><a href="./mod/mod_cache.html">mod_cache</a></code> will run before
+ <code class="module"><a href="./mod/mod_env.html">mod_env</a></code> and, when successful, will deliver the
+ content without it. In that case a cache hit will log
+ <code>-</code>, while a cache miss will log <code>1</code>.</p>
+
+ <p>In addition to the <code>env=</code> syntax, <code class="directive"><a href="./mod/mod_log_config.html#logformat">LogFormat</a></code> supports logging values
+ conditional upon the HTTP response code:</p>
+
+ <pre class="prettyprint lang-config">LogFormat "%400,501{User-agent}i" browserlog
+LogFormat "%!200,304,302{Referer}i" refererlog</pre>
+
+
+ <p>In the first example, the <code>User-agent</code> will be
+ logged if the HTTP status code is 400 or 501. In other cases, a
+ literal "-" will be logged instead. Likewise, in the second
+ example, the <code>Referer</code> will be logged if the HTTP
+ status code is <strong>not</strong> 200, 204, or 302. (Note the
+ "!" before the status codes.</p>
<p>Although we have just shown that conditional logging is very
powerful and flexible, it is not the only way to control the
log file typically grows 1 MB or more per 10,000 requests. It
will consequently be necessary to periodically rotate the log
files by moving or deleting the existing logs. This cannot be
- done while the server is running, because Apache will continue
+ done while the server is running, because Apache httpd will continue
writing to the old log file as long as it holds the file open.
Instead, the server must be <a href="stopping.html">restarted</a> after the log files are
moved or deleted so that it will open new log files.</p>
In order to write logs to a pipe, simply replace the filename
with the pipe character "<code>|</code>", followed by the name
of the executable which should accept log entries on its
- standard input. Apache will start the piped-log process when
+ standard input. The server will start the piped-log process when
the server starts, and will restart it if it crashes while the
server is running. (This last feature is why we can refer to
this technique as "reliable piped logging".)</p>
for this purpose. For example, to rotate the logs every 24 hours, you
can use:</p>
- <div class="example"><p><code>
- CustomLog "|/usr/local/apache/bin/rotatelogs
- /var/log/access_log 86400" common
- </code></p></div>
+ <pre class="prettyprint lang-config">CustomLog "|/usr/local/apache/bin/rotatelogs /var/log/access_log 86400" common</pre>
+
<p>Notice that quotes are used to enclose the entire command
that will be called for the pipe. Although these examples are
<p>As with conditional logging, piped logs are a very powerful
tool, but they should not be used where a simpler solution like
off-line post-processing is available.</p>
+
+ <p>By default the piped log process is spawned without invoking
+ a shell. Use "<code>|$</code>" instead of "<code>|</code>"
+ to spawn using a shell (usually with <code>/bin/sh -c</code>):</p>
+
+ <pre class="prettyprint lang-config"># Invoke "rotatelogs" using a shell
+CustomLog "|$/usr/local/apache/bin/rotatelogs /var/log/access_log 86400" common</pre>
+
+
+ <p>This was the default behaviour for Apache 2.2.
+ Depending on the shell specifics this might lead to
+ an additional shell process for the lifetime of the logging
+ pipe program and signal handling problems during restart.
+ For compatibility reasons with Apache 2.2 the notation
+ "<code>||</code>" is also supported and equivalent to using
+ "<code>|</code>".</p>
