Usage Tracking System Settings
Administrators use these options to specify how to monitor system usage. For example, you can set the number of rows that you want stored in the usage tracking tables.
Note:
In Oracle BI Enterprise Edition 12c, you set options in configuration files to configure usage tracking. If you upgrade from Oracle BI Enterprise Edition 12c to Oracle Analytics Server, usage tracking settings are preserved and usage tracking continues to work but no values are displayed on the System Settings page, that is, they appear blank. You don't have to re-enter your usage tracking details through System Settings but, for clarity, you might decide to do so.
See Set Usage Tracking Parameters.
Note: See Recommended Configuration Settings for Usage Tracking using SQL Server.
