Watchdog: monitor your site

Note that starting with Drupal 6.x Watchdog has been replaced by the dblog and syslog modules. Dblog is similar to watchdog; Syslog allows Drupal's logging to be integrated with the server's syslog facility.

The watchdog module monitors your system and records system events in a log you can review. This helps you get a quick overview of activity on your site. Since the log records events in sequence, it can also be useful for debugging site errors.

The watchdog log records errors, warnings, usage data, performance data, and operational information. You can filter the entries ("Filter by message type") to view only a particular type of message.

You should check the watchdog report regularly to make sure your site is working properly.

You can

• view watchdog logs at Administer >> Logs >> Recent log entries (admin/logs/watchdog).
• configure the length of time logs are archived at Administer >> Site configuration >> Error reporting (admin/settings/error-reporting).
