# Monitoring SMS storage groups space

This topic describes the workspaces that monitor the status of SMS Storage Groups Space. You access these workspaces through the SMS Storage Groups Space node in the Tivoli® Enterprise Portal.

See the Monitoring the performance of user DASD groups section for information on how to add, edit, and delete a user DASD volume group.

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 SMS Storage Groups Space 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 SMS Storage Groups Space 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.

## SMS Storage Groups Space workspace

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

The direct situation analysis feature is available for this workspace. The feature can help you analyze and understand a problem that is displayed in this workspace. See Directly monitoring situations.

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.
  SMS storage groups space table view
    The table view contains one row of data for each SMS storage group. The view contains the following information:
    - The group name
    - The storage group status
    - The type and whether or not it is enabled
    - The number of volumes in the group
    - The status of the VTOC index
    - The lowest freespace percent of all volumes in the group
    - The highest fragmentation index of all volumes
    - The largest free extent
    - The total free space and the percent of free space for the group
    - The total amount of space for the entire storage group
  Storage groups with free space % < 10 bar graph
    This graph contains one bar for each storage group with a combined free space percentage that falls below 10%.
