About log files
Log files are where your site records events, such as requests, updates, or problems. Drupal and its stack have a number of log files that can help you determine what's happening with your site and where problems are coming from.
For information on how to get to Acquia Cloud logs, see About Acquia Cloud logging. You can also stream your logs in real time. In general, each log has a specific set of issues it's responsible for tracking, and you can review these logs when attempting to troubleshoot issues. For a list of each log's information, see the preceding About Acquia Cloud logging link.
These log files contain the commonly encountered messages. Each of these links presents a list of messages, what they indicate, and what you can do about them.
- Apache access log - access.log
- Apache error log - error.log
- PHP error log - php-errors.log
- Drupal page request log - drupal-requests.log
- Cron log - see Using Cron to schedule tasks
- Other logs
Drupal has other logs, some of which you may or may not have access to, depending upon the hosting platform your website uses. If your website is using Drupal core's Database Logging module (dblog), you'll be able to review certain log entries through the administrative interface under Reports. Since this module can cause performance issues on an active website, Acquia Support recommends disabling the dblog module in favor of the syslog module, which writes to a log file directly on your server.
If you're experiencing issues with a certain webpage on your Acquia Cloud website and need only the watchdog log messages for that particular webpage, see Locating Drupal watchdog log messages for a specific webpage.
