Dataset Attributes System Summary
The Dataset Attributes System Summary attributes provide summary data representing all volumes and data sets encountered in a collection cycle. One row exists in this table. The data in the row is refreshed at each collection cycle. See Dataset Attributes Database for more information.
Allocated GB: The total GB allocated to all data sets on all volumes.
Allocated MB: The total MB allocated to all data sets on all volumes.
Allocated Tracks: The total tracks allocated to all data sets on all volumes.
Available GB: The total GB available on all volumes encountered.
Available MB: The total MB available on all volumes encountered.
Available Tracks: The total tracks available (in other words, device capacity) on all volumes encountered.
Collection End Time: The date and time of day when the last collection cycle ended.
Collection Start Time: The date and time of day when the last collection cycle began.
Datasets Processed: The total number of data sets on all volumes that were processed during the collection cycle.
Largest Dataset Allocated GB: The size of the data set with the largest amount of allocated space in GB.
Largest Dataset Allocated MB: The size of the data set with the largest amount of allocated space in MB.
Largest Dataset Allocated Tracks: The size of the data set with the largest amount of allocated space in Tracks.
Largest Dataset Allocated Volumes: The number of volumes on which space has been allocated for the dataset with the largest amount of allocated space.
Largest Dataset Name: The name of the data set with the largest amount of allocated space.
Largest Dataset Volume: Volume on which the data set with the largest amount of allocated space is located.
Largest Unused Space Dataset Allocated Volumes: The number of volumes on which space has been allocated for the dataset with the largest amount of allocated and unused space.
Largest Unused Space Dataset GB: The size of unused space in GB within the data set with the largest amount of allocated and unused space.
Largest Unused Space Dataset MB: The size of unused space in MB within the data set with the largest amount of allocated and unused space.
Largest Unused Space Dataset Name: The name of the data set with the largest amount of allocated and unused space.
Largest Unused Space Dataset Tracks: The size of unused space in Tracks within the data set with the largest amount of allocated and unused space.
Largest Unused Space Dataset Volume: Volume on which the data set with the largest amount of allocated and unused space is located.
Managed System: An internal node name used to identify the system from which this row of data was obtained.
Oldest Reference Dataset Age: The number of days that oldest data set has gone unreferenced. The reference date must be non-zero. In other words, data sets that have never been referenced are not counted.
Oldest Reference Dataset Allocated Volumes: The number of volumes on which space has been allocated for the oldest dataset (where reference date is non-zero, that is, not counting never referenced datasets).
Oldest Reference Dataset Name: The name of the data set with the largest number of days since last reference. The reference date must be non-zero. In other words, data sets that have never been referenced are not counted.
Oldest Reference Dataset Volser: The volume on which the data set with the largest number of days since last reference is located.
Percent Allocated: The percentage of all available space that is allocated.
Percent Free: The percentage of all allocated space that is allocated but unused.
Percent Used: The percentage of all allocated space that is in use.
Status Message: Status of the Dataset Attributes Database data collection process.
Timestamp: The time that the table row was created.
Unused GB: The total GB allocated but unused by all data sets on all volumes.
Unused MB: The total MB allocated but unused by all data sets on all volumes.
Unused Tracks: The total tracks allocated but unused by all data sets on all volumes.
Used GB: The total GB used by all data sets on all volumes.
Used MB: The total MB used by all data sets on all volumes.
Used Tracks: The total tracks allocated and used by all data sets on all volumes.
Volumes Online: Total number of DASD volumes that were online at the time that collection ran on the system.
Volumes Processed: The total number of volumes processed.
