GUI Overview – General

The GUI allows users working on any machine to administer, operate or monitor servers and resources in any cluster as long as they have the required group memberships on the cluster machines. (For details, see Configuring GUI Users. The GUI Server and Client components are described below.

GUI Server

The GUI server communicates with GUI clients using Hypertext Transfer Protocol (HTTP) and Remote Method Invocation (RMI). By default, the GUI server is initialized during LifeKeeper startup, but this can also be configured — see Starting/Stopping the GUI Server.

GUI Client

The GUI client can be run as an application.

The client includes the following components:

• The status table on the upper left displays the high level status of connected servers and their resources.

• The properties panel on the upper right displays detailed information about the most recently selected status table object.

• The output panel on the bottom displays command output.

• The message bar at the very bottom of the window displays processing status messages.

• The context (in the properties panel) and global toolbars provide fast access to frequently used tasks.

• The context (popup) and global menus provide access to all tasks.

Exiting GUI Clients

Select Exit from the File Menu to disconnect from all servers and close the client.
