diagnostic information and record any errors that it encounters in processing requests. It is the first place to look when a problem occurs with starting the server or with the operation of the server, since it will often contain details of what went wrong and how to fix it. The error log is usually written to a file (typically error_log on unix systems and error.log on Windows and OS/2). On unix systems it is also possible to have the server send errors to syslog or pipe them to a program. 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. [Wed Oct 11 14:32:52 2000] [error] [client 127.0.0.1] client denied by server configuration: /export/home/live/ap/htdocs/test 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 LogLevel 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.

This can be configured in /etc/php5/apache2/php.ini You can also define a specific error log file for each VirtualHost in Apache. If you have any VirtualHost defined in /etc/apache2/sites-available/ and enabled in /etc/apache2/sites-enabled (enable with sudo a2ensite [your-virtualhost-definition-file]), you can change the error log by adding the following line inside your VirtualHost config: ErrorLog ${APACHE_LOG_DIR}/[your-vhost]-error.log That might be useful if you have a lot of vhosts and want to split where they report the errors. Also, you can watch your error log live by issuing the following command (adapt to your own log file if different from the default): sudo tail -f /var/log/apache2/error.log For more information check out the following lin
