Symantec Messaging Gateway contains a utility (Expunger) that purges old report data and Dashboard data. You can configure the amount of time report data is kept before it is purged.
Symantec Messaging Gateway performs better when you configure it to store less report data. Try to balance your reporting needs against the performance of Symantec Messaging Gateway. You can accomplish this balance by adjusting the retention period and the types of report data to store.
Modify how long Symantec Messaging Gateway maintains report data.
By default, report and Dashboard data is retained for seven days. If Symantec Messaging Gateway already has seven days of data, the oldest hour of data is deleted as each new hour of data is stored. Based on your organization's size and message volume, the disk storage requirements for report data can become quite large.
Specify when the Expunger utility begins the purge process and how frequently the purge process occurs.
The Expunger lets you keep the report data that is maintained at a manageable size. Because it is resource intensive, you may want to configure the Expunger to run at off hours. Report data that is purged cannot be retrieved.
Based on your organization's size and message volume, the disk storage requirements for reports data can become quite large. You can delete all of the report data that Symantec Messaging Gateway has retained at one time. Once the data is deleted, it cannot be retrieved. If you are unsure about deleting all of the report data, you can delete data based on a specified time range.
