When the <em>Enable access log</em> setting on the <a href="@accesslog">access log settings page</a> is enabled, data about every page accessed (including the remote host's IP address, referrer, node accessed, and user name) is stored in the access log. The access log must be enabled for the <a href="@recent-hits">recent hits</a>, <a href="@top-referrers">top referrers</a>, <a href="@top-pages">top pages</a>, and <a href="@top-visitors">top visitors</a> log pages to function. Enabling the access log adds one additional database call per page displayed by Drupal.
