Web Logs

Error logs and immediate access to Web access logs

Web server logs for most CSAIL Web servers are available to Lab members by logging in to the appropriate Web server (courses, groups, legacy, mit-only, people, or projects). Access logs are in /var/log/apache2/access.log and error logs are in /var/log/apache2/error.log, on local disk of each web server, where they are updated in real time.

Isolation of scripting or access errors is best done by searching for a time, IP address, and/or URL in those files corresponding to the requests that fail. Specifically, any time your browser shows “500 Internal Server Error”, this means that a more informative error message has been written to the server’s error.log.
