Workspace characteristics
Every Navigator item has at least one predefined workspace that you can open. Every workspace characteristics such as editable properties and views.
Views
A view is a pane, or frame, in the workspace containing a chart or table showing data from one or more monitoring agents. Other types of views such as the topology view and graphic view can give a broader overview of the network. Specialized view such as the browser view and terminal view are also available. You can increase the number of views in a workspace by splitting a view into two separate views.The data for a table, chart, or relational table-based topology view is chosen by the query it uses. Collectively, they are called query-based views. The query specifies the attributes to include in the view. Although each view uses one query, you can add more views to the workspace, and each can use a different query. The queries can be for different monitoring agents, including those for the Tivoli® Enterprise Monitoring Server for showing information that is common to your monitored environment (such as all the managed systems and all the situation events). You can also include queries of JDBC or ODBC data sources by writing custom SQL queries.
Links
The link feature enables you to define a link from one workspace to another. Then you can quickly jump to a related or more detailed workspace to investigate system conditions.The simplest type of a link originates from the Navigator item: When you right-click that Navigator item, the pop-up menu shows the defined links for the item. Select one to open the linked workspace.
A more specific link originates from a table or from a chart data point to another workspace. Information from one of the attributes in the selected row, bar, pie segment, or plot point is used to determine the content of the target workspace.
You can also define more complex links and use the predefined links that come with your IBM® Tivoli Monitoring product.
Navigator level
The monitoring agents available for reporting in a workspace are those assigned to that branch of the Navigator. If you are not sure which monitoring agents are included, do one of the following:- Expand the branch of the Navigator
- Right-click the Navigator item and select Properties to see which managed systems are assigned.
- Open one of the workspaces at the enterprise, platform, or system level of the Navigator Physical view
This same principle applies to attribute groups. The lowest level of the Navigator Physical view,
for example, is the attribute level. The views you can show for the workspaces at that level can
draw only from the attribute groups represented by that level. If you were to build a workspace for
the 
Disk Navigator item, for example, you could create a chart with data from the
Logical Disk attributes and another with data from the Physical Disk attributes.
