**Retain web and traffic statistics** Sets a period (in months) for which reports on the subscription’s web statistics (generated by the selected web statistics component) and traffic statistics (generated by Plesk) should be available.
Note The setting **Retain web and traffic statistics** is not changed in subscriptions when you update it for a service plan. The only way to update this setting for each domain is changing it in the Plesk database. See this KB article for more details.
**Log rotation** Enables automatic cleanup and recycling of web server log files. You can also switch on compression of processed log files and sending them to a specific email address.
