Modify a Multitrend View

Multitrend views are customizable views that let you combine trend data from multiple interfaces in a single line trend chart. You can compare the data from up to 12 interfaces in a single multitrend view. You can use multitrend views to view data from multiple interfaces in a group, from the interfaces in your inventory with the worst performance metrics, or from the interfaces on a single device.

Use multitrend views to understand performance metric trends within a device or group of managed items. For example, you can compare the utilization trends for ten interfaces on a card by adding their trend metrics to a single view. A different-colored line in the line trend chart represents each interface.

Note: Multitrend views require a larger amount of page space than other types of views. If you want to add a multitrend view to a dashboard, add it to a wide (multiple-column) area in the layout. Do not add a multitrend view to a single-column section on a dashboard layout.

Follow these steps:

1. Open the Interfaces Trends dashboard page.

   Three multitrend views appear on the page.

2. Select the view that you want to edit.

   By default, data from all groups is included in the view.

   Data from the top 12 interfaces with the most severe performance metrics is reflected in the chart on the first page of the view.

3. Click the Edit icon on the multitrend view, and select Edit.

   The View Settings dialog opens. All settings have defaults, but you can change them if desired.

4. Replace the default view Title and Subtitle with text to describe the multitrend view.
5. Select another Metric Value from the drop-down list. The Metric Value determines the units, such as "Percentage" or "Bytes".
6. Change the Direction Settings, which affect the data that is included. Select one of the following settings:
   • In and Out (data from both directions of interface flow)
   • In (inbound data only)
   • Out (outbound data only)

   Note: These options are specific to multitrend view types.

7. Change the Sort Direction, which is Descending order (highest values first) by default. The sort direction determines which interfaces are reflected in the first pages of trend charts.
8. Select one of the following options for the Y-axis of each trend chart:

   Standardized axis: Fixed at 0 to 100

   Maintains a static range, 0 through 100, for the Y-axis.

   Standardized axis: Calculated

   Lets the Y-axis adjust dynamically, based on the range of metric values that are included. The calculated setting is applied to all charts in the view.

   Standardized axis: Scale per Chart

   Let the Y-axis adjust dynamically, based on the range of metric values for each chart in the view. The Y-axis is scaling is independent, and the scaling of one chart in a view does not affect the scaling of any other chart.

9. Select one of the following options for the Chart Display Order:

   Display by Metric

   Sorts the interface charts by metric value, with the highest (most severe) values shown first, top to bottom.

   Display by Name

   Sorts the interface charts in alphanumeric order, by interface name.

   Note: Each time 12 interfaces are included in a trend chart, a new chart is created on a separate multitrend view "page". A limit of ten pages is enforced.

10. 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.

11. Select the appropriate Business Hour 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.

12. Select another Context Type from the drop-down list, such as Router or Switch.

    Only items of that selected type are queried for interface data.

13. Select another managed item or group in the Context Settings area.

    Data from the new item or group will be shown in the view.

14. Select the scope of your changes from the Apply Changes drop-down. 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.

15. Click Save.

    The view refreshes to reflect your updates.
