How can a dashboard be defined for only a specific host?
Vantage
Here is a very 'basic' process for creating dashboards, of which any object itself can be connected to one or more hosts, and any dashboard can have multiple panes/views, each of these views supplying data from one or more hosts:
How to get a dashboard only for a specific host connection:
1) Select the 'Dashboards' icon in the left pane (3rd icon from top of the icon list).
2) In the main pane of the browser window, select the '+' icon in the upper left corner of this pane. This will display a tab titled 'Dashboard'.
3) Inside each new pane that is created (based upon the layout that was selected), the field 'Object:' will be displayed. Select which object to display for this given pane.
4) For each object/pane that is displayed, select the 'gear' icon in the upper right section of this view/pane. This will display various things like Filter, Sort, etc. Select 'Hosts', and this is where you can determine which hosts are used for this object. Each pane of the dashboard can be connected to different objects/hosts, and a single view/pane can contain data from one host or multiple hosts.
