This image shows the PeopleSoft Application home page within Stack Monitoring.  On the right of the screen are resources links to view the Performance (shown), Alarms, Topology, and Configuration pages for the application stack.
The main pane of the page has a refresh button under the resource name which can be used to update the discovered members of the application as well as a more actions button which includes options to add tags to the resource, configure top metrics, and create a maintenance window for the stack.  On the top right of the screen is a time selector for the metric period as well as an optional setting for auto refresh interval as well as a manual refresh button to update the metrics shown.
Next down the page is a set of tiles showing the resource type, license edition chosen, and the unique identifier within Oracle Cloud (ocid).  A second tile shows a donut chart of related resources, colored green to show the number which are up, red for any which are down, or gray for any which are not reporting a status.  The center of the donut shows the count of all related resources.  On the right side of this row of tiles is the Alarms summary, showing a total count of alarms and a breakdown between critical, warning, and error where each count is clickable to open a list of the related alarms.
Below the tiles is a time slider with handles to narrow the time range shown in the metric graphs on the page in order to zoom in and see more detail.
Below the time slider are the metric graph tiles, shown in collapsible sections for each tier of the application stack.  Shown in this image is just the Application Server Domain section.  Each section has a dropdown to select a particular instance of that component. In this case, the PSFT_HCM App Domain is selected and the graphs shown relate to that domain for the time period chosen in the time selector and optionally adjusted by the time slider.  The metrics shown in these tiles include the health (ok, warning, or critical), the system load (idle, light, medium, or heavy), and the count of running servers by name.
Numerous other metrics exist for the components of the application stack but are below the cutoff of the screen capture.
