Databases can be substantially overloaded with all alerts, packet logs, any incident reports that have been generated, and audit and fault logs. Maintenance of this data can be accomplished automatically using the File Maintenance scheduler.
If automatic File Maintenance is used to delete alert and packet log data it is recommended that a large value, such as 90 (as in 90 days), is entered in the "Scheduled Deletion" column for the Alert & Packet Log Data option. This allows for long-term analysis of alerts and logs without overloading your database with millions of alerts, which may affect long-term and overall database performance. By setting the value to 90 days, all alerts and packet logs older than 90 days are deleted at the weekly maintenance scheduler time.
Apart from the database data, Manager creates a group of administration files that must be maintained regularly. These include Diagnostic files, DoS files (profiles) and Data Mining files (for Trend Reporting) among others. It is a best practice to schedule the deletion of the oldest of these files on an on-going basis. This can be accomplished using the Maintenance scheduler.
