Selecting data views from the navigation tree
Using the navigation tree in Graph Explorer, you can view the details of each of the following data type objects in Graph Explorer:
- Physical systems
- Logical systems
- Coupling facilities (structure data available for baselines only)
- Applications
- Workloads Disks
- Tapes
- Storage system
- Storage group
The full navigation tree is displayed to the left of the graph workspace when you load a baseline or scenario into the Graph Explorer, as shown in the following figure.
To drill down in the navigation tree of the Graph Explorer, double-click any name that is next to a plus sign, or an icon with a down arrow. The tree expands to show the contents of the contained object.
Example of navigating in the tree
Click the Logical Systems item in the navigation tree to expand the view and display a list of all logical systems, as shown in the following figure.
In the following figure, the logical systems for which more information is available are marked with a down arrow and a plus sign. For example, click the BMCC logical system to open that object and view the associated processors, workloads, coupling facilities, disks, and tapes. 
Any object in the navigation tree that has a plus sign next to it means that you can drill down further by double-clicking it, for example, the Processors, Workloads, Coupling Facilities, Disks, and Tapes items in the figure. The absence of a plus sign or down arrow next to a workload name indicates that you have reached the maximum drill down point in the tree.
