The Private Service Edge dashboard (Analytics > Reports > Private Applications > Private Service Edge) provides information about the Private Service Edges for Private Applications for your organization.

See image.

Dashboard Tools

The Private Service Edge dashboard displays the following information and functionality:

• Time Period Filter: View user data over a period between 30 Mins to 14 Days, or you can select Custom Range to specify a custom start and end date. If you use Custom Range, the start date can be within the last 14 days. This filter applies to all widgets on the dashboard. By default, the dashboard displays information for events that occurred in the past 30 minutes.

Due to the way data is aggregated for different time period filters, the same point in time in an Activity Monitor widget might show slightly different values depending on the time chosen. For example, the data with the 30 Mins time period filter at 3:00 PM might not match the data with the 14 Days time period filter for the same date at 3:00 PM.

• Refresh Icon: Refresh the dashboard to reflect the most current information. The page displays the most recent information from the last 5 minutes.

Widgets can show solid lines or dashed lines. Solid lines represent actual data for the time period. Dashed lines indicate the expected trajectory of the data, but it isn't actual data. You can select a point on the lines in a widget to see the exact date, time, and relevant numbers for the Private Service Edges as related to the particular widget. You can also click View Logs to see the User Activity Diagnostic logs page filtered for the Private Service Edges for Private Applications in the widget.

Filtering Private Service Edges

You can filter the Activity Monitor charts and Private Service Edge Details table by selecting the Private Service Edges you want to review. The filters available are Private Service Edge and Private Service Edge Groups.

See image.

When filtering by Private Service Edges and Private Service Edge Groups, the selected Private Service Edges and Private Service Edges within the selected Private Service Edge Groups are shown.

The filters between Private Service Edges and Private Service Edge Groups use the OR operator, instead of AND, to help compare Private Service Edges in Private Service Edge Groups.

There is a limit of 25 Private Service Edges you can select at one time. If you haven't selected any Private Service Edges and have selected a Private Service Edge Group that contains more than 25 Private Service Edges, then the first 25 Private Service Edges for the selected Private Service Edge Group are used in the filter. If you select Private Service Edges and then select Private Service Edge Groups in a way that exceeds the limit, an error message appears and you must adjust your selection.

Within the Private Service Edge Group filter, you can see the number of Private Service Edges associated with the Private Service Edge Group.

See image.

If no Private Service Edges are selected, the top Private Service Edges from the Peak Memory Utilization chart are selected by default.
