    Item Description
    Node List includes all nodes in the cluster. For a stand-alone server, only one node will appear in the list.

    By default, the graphs on this page display system performance data for the first cluster node of the cluster; however, you can select a specific node from the drop down list in order to view its unique performance data.

    At any time, to display the performance information for a node other than the one currently being displayed, select the node from the list.
