Modify a Custom IM MultiTrend

IM Multitrend is a customizable chart that lets you analyze the same metric for multiple devices in a group using a single chart. For example, you can compare the utilization trends for ten interfaces on a card by adding their trend metrics to a chart. A different-colored line in the line trend chart represents each interface.

Note: Multitrends require a larger amount of page space than other types of charts. 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 to a single-column section on a dashboard layout.

Follow these steps:

1. Open the dashboard page where you want to place the custom IM multitrend.
2. Click More, Edit Dashboard.

   The Edit Dashboard Layout page opens.

3. Expand the Custom View - Infrastructure Management category.

   Several options appear for this category.

4. Select IM Device MultiTrend. If you are already in the device context, select IM Multitrend.
5. Drag the chart to the layout, and drop it where you want it to appear.
6. Click Save.
7. You return to the dashboard. A basic multitrend container has been added to the page.
8. Click the Edit icon on the multitrend view, and select Edit.

   The View Settings dialog opens.

9. Replace the default view Title with a description of the multitrend view.
10. Select a Metric Family and a Metric Value metric from the lists. A metric family and its associated metric values define what data is collected and reported on for a given technology or device.

    Note: By default, filtering is enabled to display only metrics that are consistent with the default roll-up strategy. To select metrics that do not conform, clear the Metric Filtering check box. When the selected metrics do not conform, the dialog displays an informational message in the header.

11. Change the Sort Direction, which is Descending order (highest values first) by default. The sort direction determines which metrics appear at the top of the page.
12. Edit the remaining options as needed, for example:

    Resolution

    The Resolution is the amount of time that each data point represents.

    Chart Type

    • Trend Chart: Renders a traditional trend line for each device or component metric.
    • Stacked Chart: Renders a stacked line on top of each other for each device or component metric.

    Standardized axis

    • Fixed at 0 - 100: Maintains a static percentage range for the Y axis.
    • Calculated: Let the Y axis adjust itself dynamically, based on the range of metric values that are included.

    Chart Display Order

    • Display by Metric: Sorts the charts by metric value, with the highest (most severe) values shown first, left to right.
    • Display by Name: Sorts the charts in alphanumeric order, left to right, by name.
13. Select by Component or by Device for the Metric Calculate Level field. This selection determines whether you see aggregated trends calculated at a device level or a component level when you drill down from the IM Multitrend chart.
14. Select the number of trend lines to display on each chart. The trend lines represent the top device components with the most severe performance metrics.
15. Select the maximum number of charts for the multitrend views. The query results display one chart per page.
16. Select the 'Metric Filtering' checkbox to filter the 'Metric Value' field. Metrics fall into two categories: those that can be counted, such as bits and bytes, and those that provide a gauge of utilization based on a rollup of data. Only those that provide a gauge are suitable for this view.

    When the checkbox is Enabled (which is the default), the 'Metric Value' field displays only those metrics that conform to the needs of a data rollup. You can clear the checkbox to see all possible metrics for the selected 'Metric Family.' Those metrics that do not conform are flagged with a warning.

17. (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.

18. 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.
19. 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.

20. Click Save.

    The view refreshes to reflect your updates.
