+The first argument defines a file that will store the log.
+<!--
+If filename is not absolute, it is prefixed with the prefix path.
+-->
+</para>
+
+<para>
+The second argument determines the level of logging.
+Log levels above are listed in the order of increasing severity.
+Setting a certain log level will cause all messages of
+the specified and more severe log levels to be logged.
+For example, the default level <value>error</value> will
+cause <value>error</value>, <value>crit</value>,
+<value>alert</value>, and <value>emerg</value> messages
+to be logged.
+<note>
+For <value>debug</value> logging to work, nginx needs to
+be configured with <code>--with-debug</code>.
