Application Servers Monitor Views

The Application Servers Monitor dashboard provides a high-level overview of your monitored environment that is divided into five main views: Systems, Servers, Deployed Applications, Requests, and Methods. You can drill down from any of these main views for more information about a selected component.

Hover your mouse over any text on the dashboard to determine whether it is a link, and click any link to open a pop-up or view.

To drill down to a view:
1
On the Application Servers Monitor dashboard, click a tile (Systems, Servers, Deployed Applications, Requests, or Methods).
2
In the selected tile view, click the name of the item you want to investigate.
For example: click the Servers tile, select a WebLogic® server, and click the Web Applications link under Applications Components. A pop-up appears, listing the health status of the selected component.
3
In the upper left corner of the pop-up, click Web Applications to open the drilldown view in the display area.
 
* 
TIP: Use the breadcrumb trail at the top of any drilldown view to return to the Application Servers Monitor dashboard.
