# Monitoring Dataset Attributes System Summary data

This topic describes the workspaces that monitor the status of Dataset Attributes System Summary data. You access these workspaces through the Dataset Attributes System Summary node in the Tivoli® Enterprise Portal.

See Workspaces for general information on predefined workspaces and a list of all nodes that are included in the Tivoli OMEGAMON XE for Storage on z/OS product. Each node corresponds to a specific area of storage resource monitoring. And each node includes links to a unique set of storage resource workspaces. See Accessing workspaces to learn about navigating among workspaces. And see Integration with other products to learn about linking to the workspaces of other IBM Tivoli Monitoring products.

## Navigating the workspaces of the Dataset Attributes System Summary node

This section summarizes the workspace links that are available through the Navigator node. Depending on your monitoring goal, you follow a specific series of links to get detailed information about storage resources.

You start in the Dataset Attributes System Summary node to navigate to the workspaces that you see in Table 1. You can access the workspaces in this table using the standard path and method for navigating workspaces.

## Dataset Attributes System Summary workspace

This topic describes the main components of the principal workspace for this node.

This workspace provides the principal view of the Dataset Attribute Database, which maintains data on data set attributes related to space, DCB, and cataloging. For more information about the Dataset Attribute Database feature, including how to configure it and how to work with groups to monitor a collection of data sets based on specific attributes, see Dataset Attributes Database.

Note: Data collection is turned off by default, so this workspace is initially empty.

Views
  This workspace provides the following views. For a description of the attributes used as column headings in the workspace table view, review the attribute group definitions for this workspace in the online help. The help resource includes attribute descriptions that are displayed when you hover with the mouse pointer over a column heading.
  Table view
    The table view displays one row of data for each resource. The columns show the following attributes:
    - Volumes online
    - Volumes processed
    - Datasets processed
    - Available tracks
    - Allocated tracks
    - Used tracks
    - Unused tracks
    - Percent of available allocated
    - Percent of allocated used
    - Percent of allocated free
    - Name of largest data set
    - Size of largest data set
    - Name of data set with largest unused space
    - Amount of space unused by largest data set
    - Name of data set with oldest reference date
    - Number of unreferenced days for oldest data set
    - Number of uncataloged data sets
    - Collection start & end date/time
