The Teradata Viewpoint Data Mover portlet is the designated interface for managing and monitoring Data Mover jobs. When a job is selected within this portlet, several tabs become available to provide detailed information. The 'Log' tab specifically displays the contents of the job's log file. This log contains a comprehensive record of the job's execution, including the number of rows processed and the total data volume (bytes) read and written, thereby allowing an administrator to monitor the amount of data transferred.

A. The Completed Queries portlet tracks executed SQL queries. A Data Mover job is a utility process, not a single query, so its specific transfer volume statistics are not found here.

C. The Performance Data Collection portlet is used for analyzing historical system performance data (PDCR), not for monitoring the specific, real-time metrics of an individual Data Mover job.

D. The datamove status command is a command-line interface (CLI) utility. The question explicitly requires a method to monitor the job via Viewpoint, making this option incorrect.

1. Teradata® Viewpoint User Guide, Release 16.20. In the chapter "Standard Portlets," the section on the "Data Mover" portlet describes its functionality. It details that after selecting a job, the "Log" tab can be used to view the job's log file, which contains detailed execution statistics. (Reference: B035-2206-162K, Chapter 10: Standard Portlets, "Data Mover," Page 315).

2. Teradata® Data Mover User Guide, 16.20. This guide explains the contents of the job log files. It specifies that the log file contains detailed information about the job execution, including "Total bytes read" and "Total bytes written," which represent the data volume transferred. The Viewpoint portlet provides a direct view of this log. (Reference: B035-2034-162K, Chapter 5: Monitoring Data Mover Jobs, "Job Log Files," Page 78).
