      The size of the data actually retained by the collector is always larger than the specified number because data clean up only drops table partitions that exceed this number. A 1024 byte kilobyte is used, so 1 GB is actually 1,073,741,824 bytes.
    Teradata Viewpoint uses a retention policy to keep collected data for a time period or up to a certain size. For more information, see Data Collector Sample Rates.
  12. Click Apply.
    If the operation is successful, "" appears. If the operation fails, "" appears. If you receive an error, verify that the settings are correct and try again.
