The ResUsageSvdsk table:
  • Provides AMP-level storage statistics.
  • Includes resource usage logs on cylinder allocation, migration, and I/O statistics.

If you enable table logging on ResUsageSvdsk, a row is written to the database once for every AMP vproc in the system for each log interval. To consolidate and summarize the total number of rows written to the database, you can enable Summary Mode. For details, see Summary Mode.

This table is created as a MULTISET table.

Teradata recommends that you use ResSvdskView to access the data rather than accessing the ResUsageSvdsk table directly. For more information, see Resource Usage Views Overview.
