These parameters (located at **Service Plans** \> select a plan \> **Logs & Statistics** tab) define how statistics and logs of a subscription should be stored.
**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
These settings in subscriptions are not synchronized with service plans.
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.
