Viewing the Private Cloud Controllers Dashboard

The Private Cloud Controllers dashboard provides information about the Private Cloud Controllers for your organization.

Dashboard Tools

The Private Cloud Controllers 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 show solid lines that represent actual data for the time period. You can select a point on the lines in a widget to see the exact date, time, and relevant numbers for the Private Cloud Controllers as related to the particular widget. You can also click Show All Labels to show or hide the particular labels for the Private Cloud Controllers in the widget.

A (+) icon appears as you move over the widgets. Use this icon to select the time period to zoom in for greater detail. A blue box shows the chosen portion of the widget, and the widget shows this selected smaller time period.

Click Zoom Out to view the original widget.

For each widget, you can deselect the listed Private Cloud Controllers to change what items are tracked within the widget. You can also search within the widget to reduce the listed Private Cloud Controllers that appear in the widget. To search, enter part or all of a Private Cloud Controller name, or use the following search query options with >, <, or = operators:

  • Name: The name of the Private Cloud Controller (e.g., name = MyPrivateCloudController).
  • Value: A numerical value specific to the widget (e.g., value < 40).

Filtering Private Cloud Controllers

You can filter the Activity Monitor charts and Private Cloud Controller Details table by selecting the Private Cloud Controllers you want to review. The filters available are Private Cloud Controllers and Private Cloud Controller Groups.

When filtering by Private Cloud Controllers and Private Cloud Controller groups, the selected Private Cloud Controllers and Private Cloud Controllers within the selected Private Cloud Controller groups are shown.

The filters between Private Cloud Controllers and Private Cloud Controller groups use the OR operator, instead of AND, to help compare Private Cloud Controllers in Private Cloud Controller groups.

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

Within the Private Cloud Controller Groups filter, you can see the number of Private Cloud Controllers associated with the Private Cloud Controller group.

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