Hoover is an graphical user interface under development, authored by Dean Johnson <firstname.lastname@example.org>. Its interface allows the user to aggregate cluster information, for one or more clusters, in a very compact space and attempts to have only one window if at all possible. The primary display (referred to as a 'panel') is a tree view of the clusters and their nodes. From that panel, the user can then find information, such as the system event logs, or perform various administrative actions on the nodes (or whole clusters), such as resetting them or powering them down. When information has been requested, typically a new panel is created in the lower tabbed panel. Panels can be dragged and dropped inside or outside of hoover for flexibility.
