This topic describes the workspaces that monitor the status of logical control units. You access these workspaces through the Logical Control Unit 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 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.
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.
The table view displays one row of data for each logical control unit configured in the reporting LPAR. The view contains the following information:
This graph contains one bar for each logical control unit. The height of the bar indicates the contention rate for the unit.
