CPU or Memory 95th Percentile Trend Scorecard View

The CPU or Memory 95th Percentile Trend Scorecard view presents the change, or trend, in 95th-percentile utilization for the indicated sub-groups during the selected time frame. These values indicate that 95% of CPU or memory utilization is at or below the value shown in the view. The 95th-percentile calculation is a well-known statistical standard that discards maximum spikes in data.

This view displays CPU metrics by default. You can edit the view to select memory metrics. The suffix of the view title changes to reflect the selected metric.

Use the following procedure to edit, or customize, the view.

Follow these steps:

1. Click the Options (gear) icon on the view, and select Edit from the menu.

   The Settings dialog opens.

2. Change the 'Metric Value' to show CPU Utilization or Memory Utilization metrics in the view.
3. Select the number of time frames to display in the view. A time frame is represented by a column of data. The default is 6 time frames. You can select from 2 to 8 time frames, or columns.
4. Change the threshold values for the metrics in the view:
   • Critical Status Start. Utilization that exceeds this value is considered critically degraded and appears with a red icon in the view. The default is 80%.
   • Moderate Status Start. Utilization that exceeds this value is considered moderately degraded and appears with an orange icon in the view. The default is 60%.
   • Minor Status Start. Utilization that exceeds this value is considered minimally degraded and appears with a yellow icon in the view. The default is 40%.
5. Use the 'Results Limit (Max Rows)' field to limit the number of table rows that appear in the view. Limiting the rows preserves monitoring-system performance. The default is 100 rows.
6. (Optional) Filter the view by time zone and business hours. Such filtering lets you monitor critical business functions during actual business hours in their respective time zones.
   1. Select the 'Time Filtering: Enabled' check box.
   2. Select the Time Zone filter that best represents the geographic location of the business function. The list contains only time zones that are associated with the configured sites for the current tenant.

      Tip: The list offers a "type ahead" feature. As you type the name of the country for a time zone, the list quickly scrolls to the time zones in that country.

   3. Select the appropriate Business Hours filter. The Options in the list are available only after you select a Time Zone filter.

      The list contains only business hours that are associated with the current tenant. However, it is not filtered by group or item context. If you have selected a context for the view, select the business hours that are associated with the applicable site. Otherwise, the view contains no data.

      Note: A CA Performance Center administrator configures all business hour selections that are available in the Business Hour Filter list.

7. Expand the nodes in the Context Settings area and then select the group whose data you want to see in the view. Your selection appears in the 'Current Item' field.
8. Select the scope of your changes from the Apply Changes list. Select one of the following options:
   • For All Tenant Users. Saves the changes so that they are only available to users associated with your tenant (possibly the Default Tenant).
   • My User Account. Saves the changes to your user account as a default for this view.
   • My Current Session. Reverts the changes when you log out.

   Note: The availability of these options depends on your user account role rights.

9. Click Save.

   The view is refreshed to reflect your updates.
