Monitoring dataset groups summary data
This topic describes the workspaces that monitor the status of Dataset Group Summary data. You access these workspaces through the Dataset Group 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 OMEGAMON 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.
In addition, with OMEGAMON for Storage on z/OS Version 4.2.0 Interim Feature 3 or later, you can issue dataset-level Storage Toolkit commands from the dataset group level. To access these commands, open the Dataset Group Summary workspace from the Navigator, right-click a row on the table view and select the Dataset Actions... menu item, then select the action you want to perform.
Dataset Group Summary workspace
This topic describes the main components of the principal workspace for this node.
The following sections describe various components of this workspace.
- 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.
- Dataset group space utilization graph
- This graph displays total free space and group total used space information for each data set group.
- Dataset group summary table view
- The tabular portion covering the entire width of the workspace
at the bottom of the screen displays one row of data for each defined
data set group. The rows contain:
- The data set group name
- The total number of data sets
- The data set with the largest allocation
- The largest space allocation
- The data set with the largest free space
- The largest space free
- The data set with the oldest referenced date within the group
- The oldest referenced date for the identified data set within the group
- The data set with the worst MSR within the group, and the highest MSR of the data set
- The total used space for all of the data sets within the group
- The total number of I/Os for all the active data sets within the group
- The total average MSR for all the active data sets within the group
- The data set group used space percentage
- The total allocated space for all the data sets within the group
- The data set group percentage of free space
- The total free space for all the data sets within the group
- Dataset group RLS summary table view
- The tabular portion covering the entire width of the workspace
at the bottom of the screen displays one row of data for each defined
data set group. The rows contain:
- The name of the dataset group.
