Monitoring SMS storage groups performance

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

See Workspaces for general information on predefined workspaces and a list of all nodes that are provided by Tivoli OMEGAMON XE for Storage on z/OS. Each node corresponds to an area of concern for the monitoring of storage resources, and the node links to a unique set of workspaces. Learn how to navigate among workspaces here: Accessing workspaces. Also see Integration with other products to learn about linking to the workspaces of other IBM Tivoli Monitoring products.

SMS Storage Groups Performance 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 performance table view
The table view contains one row of data for each SMS storage group defined in the reporting LPAR. The view contains the following information:
  • The name of the group
  • The type
  • The SMS status
  • The number of volumes in the group
  • The current highest response time for any volume in the group
  • The current high busy percent for any volume in the group
  • The device multi-processing level
  • The low read and write hit percents among all volumes in the group
  • The highest DFW retry percentage in the group
High volume response time > 25 bar graph
This graph contains one bar for each SMS storage group with a highest volume response time that exceeds 25 milliseconds. The height of the bar indicates the actual response time for that volume.
