Monitoring cache CU status

This topic describes the workspaces that monitor the status of cache CU. You access these workspaces through the Cache CU Status 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.

Cache CU Status 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.
Cache status table view
The table view displays one row of data for each cache control unit configured to the reporting LPAR. The view contains the following information:
  • The subsystem ID of the control unit
  • The control unit type
  • The number of active volumes
  • The number of deactivated volumes
  • The cache status
  • The amount of cache configured in the control unit and the amount currently available
  • The nonvolatile storage status, the amount of NVS configured and the amount pinned
  • Storage facility series
Available cache bar graph
This graph contains a bar for each cache control unit. The height of the bar indicates the amount of cache (in megabytes) available in the unit.
NVS pinned bar graph

This graph contains a bar for each cache control unit. The height of the bar indicates the amount of NVS (nonvolatile storage, in kilobytes) pinned in the unit.

Deactivated volumes bar graph

This graph contains a bar for each cache control unit. The height of the bar indicates the number of deactivated volumes on that control unit.
