Creating a Top N graph

The Top N graph is a Pareto bar graph comparing Top N resources. You can create either a Top N or a Bottom N graph.

Top N graphs compare monitored resources based on a common measurement. The Pareto bar chart includes resources with the highest average (based on the common measurement). Infrastructure Management administrator sets the number of bars in the graph. The number of bars (N) is limited to 15 items per thumbnail.

Top N graphs can be created from both the Operations Console and the Administration Console.

Computation of Top N graphs provides an order to the individual elements within each graph. Example, in the Top 10 Interface in Utilization graph, the number one graph shows the highest average for all interfaces.

To create a Top N graph

  1. In the navigation pane in the Operations Console, click Views & Graphs.
  2. In the Views & Graphs drawer, click the Custom Graphs icon.
  3. In the Custom Graphs screen, select the Top N Graph option Top_N_graph.gif.
  4. Select Group Filter.
  5. Select Monitor Type. You can select only one monitor type here.
  6. Click Next.
     The system populates the corresponding attributes in the lower pane of the screen.
  7. Select Attribute.
  8. Click Apply.
  9. On the Customs Graphs screen, select Graph Type: Top N or Bottom N.
  10. Select the number of bars from the list.
  11. Specify the duration, and select the units (Days or Hours) from the adjacent list.
  12. Select the values to be displayed: Average and High or Average and Low.
  13. Select the graph preference: 2 Dimensional or 3 Dimensional
  14. Select the schedule.
    • Click New to define a new schedule.

    • Click Editto change the selected schedule.

      Note

      The three Dimensional option is available only through the Operations Console. However, 3-dimensional graphs configured through the Operations Console retain the option during editing through the Administration Console.

  15. Click Generate Graph.

    Note

    The Forward and Backward buttons that help you view graphs corresponding to the succeeding and preceding time ranges, respectively, are not available for Top N graphs.


    The Description table located below the graph lists data resources of the Top N graph. The Num column provides a link to open the Individual graph for the resource. To modify the statistics, see Creating-a-line-or-area-graph.

To view a stacked graph for any of the listed instances

  1. Select the check box corresponding to the monitor instance.
  2. Click Generate graph.

Listing all button

Most monitored categories, such as Availability and Utilization, contain numerous devices, interfaces, and services. Clicking List All at the bottom of the Top N table expands the table to list all the resources that comprise the selected category. A list of sources used to compile the chart is displayed. The List All feature allows you to generate a maximum number of 100 items per page. You can also generate individual graphs from each of these items.
