The Overview Bar summarizes your environment in a compact space. If your view is currently filtered, the filtered objects will be displayed above the Overview Bar, as shown. Individual filtered objects can be removed by clicking the [X] next to each object. To remove all filtered objects, click Clear All.
The doughnut chart in the Overview section graphically displays the ratio of objects to one another in all possible states using indicative colored slices. The total number of objects in your environment is also displayed.
Objects under the Issues header are parsed and enumerated according to status. Objects shown here will be in one of the following distressed states: Down, Critical, Warning, Unknown and Unreachable. An icon and count will only appear if at least one object is currently in that state.
