Abstract: One embodiment of the present invention provides a computer system for use in relation with a group of nodes. The computer system includes a manager adapted for communication with a link to a network existing between the nodes, so as to access node status data and node management functions. It also includes a graphical user interface being adapted to cooperate with the manager for graphically displaying representations of nodes of the group of nodes from node status data, and representations of node management functions. The manager is also capable of responding to a user action on a representation of said node management function, for causing execution of that node management function.
