Daily logs retention refers to how long logs are stored before they are deleted. Configure this value to help you manage free disk space.
Audit logs are not deleted, even in a case of emergency disk space maintenance, regardless of the configured log retention value. You cannot configure the daily retention of audit logs.
Audit indexes are deleted only in a disk space emergency. Audit indexes are not deleted as part of daily maintenance regardless of the value configured in SmartConsole, unless they are configured otherwise in the log_maintenance_domain_conf.csv files (Global SmartEvent only).
