Chapter 3 Managing Nodes

Manage nodes by adding nodes or clusters to and deleting nodes or clusters from the main window's nodes area, moving nodes or clusters among groups, and creating and deleting groups. Monitoring nodes means looking at performance data in real time. From the main window's Tasks menu or toolbar, choose Node Management, which opens the Node Management dialog box.

See the individual task descriptions for specific procedure steps. All tasks begin from the Node Management dialog box.
