Database Tools Table Maintenance

This feature lets you purge expired data from data tables in your database. Be very careful when using this dialog, as data that is purged through this process is lost and cannot be restored.

Select tables to purge. The data tables are grouped by the purpose they serve (active monitors, report data collection, and other). Select the tables you want to purge from the three lists.
Total Rows. The total number of data rows in this table that currently holds data. This includes live and expired rows.
Expired Rows. The total number of expired data rows in this table. Expired data is data that has been rolled up, and has not yet been purged by the application or has not been reused. These are rows that are marked for deletion, or have been kept longer than needed, according to your data roll-up settings. See Program Options - Report Data for more information on setting your data roll-up settings.

Click Purge Expired Rows to remove those records from the database.
