# Dataset Attributes Catalog Summary

This group of attributes tracks the number of data sets cataloged in each system catalog. This data shows the distribution of data sets across catalogs and can allow rebalancing to improve performance.

When the Collect Catalog Data option is enabled, the catalog data is retrieved for each data set encountered in the VTOC of the volume. See Dataset Attributes Database for more information.

Allocated GB: Total allocated GB represented by all of the data sets in the catalog.

Allocated MB: Total allocated MB represented by all of the data sets in the catalog.

Allocated Tracks: Total allocated tracks represented by all of the data sets in the catalog.

Timestamp: The time that the row was created.

Total Datasets: The total number of processed data sets contained in the catalog.
Note: Data sets that are cataloged, but do not exist on any processed volume are not counted. The data sets are not counted because the data set name from the VTOC is the starting point for the catalog lookup.
