Teradata Viewpoint uses a sample rate to collect data from the system and uses a retention policy to keep the collected data for a time period or up to a certain size. The sample rate and retention policy vary for each data collector and most can be adjusted as needed.

Not applicable under the Initial Retention Policy column indicates that data collector does not store data.
