In addition, log files may contain information supplied directly by the client, without escaping. Therefore, it is possible for malicious clients to insert control-characters in the log files, so care must be taken in dealing with raw logs. Error Log Related Directives ErrorLog LogLevel The server error log, whose name and location is set by the ErrorLog directive, is the most important log file. This is the place where Apache httpd will send diagnostic information and record where are apache server logs located 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.

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.

You can see which files visitors view, how the web server responds to requests, and other information such as the web browsers visitors use. Managed dedicated servers and VPS If you have a managed Flex Dedicated Server or VPS, you can view the raw Apache access logs in cPanel. For more information about how to do this, please see this article. Semi-managed dedicated servers and VPS If you have a semi-managed Flex Dedicated Server or VPS, you have root access. This means you can manipulate and process the Apache access log files any way you want. For example, you can log in to your server using SSH and type the following command to view the last 100 lines in the access log: sudo tail -100 /etc/httpd/logs/access_log If your server is running Debian or Ubuntu, type the following command instead: sudo tail -100 /var/log/apache2/access.log To search for a particular term in the access log, use the grep command. For example, to search for all HTTP GET requests in the access log, type the following command: sudo grep GET /etc/httpd/logs/access_log If your server is rhere for a quick overview of the site Help Center Detailed answers to any questions you might have Meta Discuss the workings and policies of this site About Us Learn more about Stack Overflow the company Business Learn more about hiring developers or posting ads with us Stack Overflow Questions Jobs Documentation Tags Users Badges Ask Question x Dismiss Join the Stack Overflow Community Stack Overflow is a community of 4.7 million programmers, just like you, helping each other.
