Magento Log Tables - Admin Log Cleaning
Magento saves visitor and URL access information in its log tables (log_url, log_url_info, log_visitor and log_visitor_info). These tables can be quite large and affect site performance if they are not maintained. Majority of people already have some kind of traffic analysis tool - one of the most popular tools is free Google Analytics - and they don’t necessarily find Magento log tables very efficient.
You can set up a log cleaning cron job through Magento Admin panel.
- Go to System -> Configuration.
- Click on System from the left menu (almost at the bottom).
- Open Log Cleaning area and change the settings as you want.

A bug was reported in the 1.2.0.3 version regarding this functionality. It seems fixed and the fix should be included in the next release:
Locate app/code/core/Mage/Adminhtml/Model/System/Config/Backend/Log/Cron.php:
$time = $this->getData(’groups/log/fields/time/value’);
$frequncy = $this->getData(’groups/log/frequency/value’);
$errorEmail = $this->getData(’groups/log/error_email/value’);
Change the above codes from the function ‘_afterSave()’ to the following:
$time = $this->getData(’groups/log/fields/time/value’);
$frequncy = $this->getData(’groups/log/fields/frequency/value’);
$errorEmail = $this->getData(’groups/log/fields/error_email/value’);
(It’s missing “fields/” in $enabled, $frequncy, and $errorEmail.)
