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