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 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.
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.
