The web server maintains separate log files of all requests, errors, and CGI script errors. These log files are only accessible on [[SSH#Login_servers|login servers]] and are shared by all OCF users, so they may contain messages that do not pertain to your website. 

== Access logs ==

If you would like to see a list of who is visiting your website, check the web server error log file: <tt>/opt/httpd/logs/access_log</tt>.

To filter the access log to display only entries relating to your website, you can use <tt>grep</tt>: <pre>grep USERNAME /opt/httpd/logs/access_log</pre> where <tt>USERNAME</tt> is your login name or virtual host.

== Error logs ==

If you are having trouble with your website, please check the web server error log file: <tt>/opt/httpd/logs/error_log</tt>. Anything printed to standard error by your web pages will be redirected to the web server log file.

To see error messages in real-time, you can use <tt>tail</tt> and <tt>grep</tt>: <pre>tail -f /opt/httpd/logs/error_log | grep USERNAME</pre> where <tt>USERNAME</tt> is your login name or virtual host. Press Ctrl-C to stop log output.

== CGI logs ==

If you are having trouble with a CGI script, please check the <tt>cgiwrap</tt> error log file: <tt>/opt/httpd/logs/cgiwrap.log</tt>.

Please note that anything printed to standard error by your web pages will be redirected to the web server [[#Error logs|error log]].
