Creating a pie graph

Pie graphs show the distribution of points for specified time ranges in individual pie slices and show the distribution of values over time.

Pie graphs are best suited for getting a high-level overview of the performance of a specific attribute, because only a single instance and attribute selection is plotted. Indicators are not applicable to pie graphs. Description of slices is available in a file for each threshold or SLO at the following path: installationDirectory/usr/pw/pronto/conf/piebuckets.xml. Different slices are available for Major, Minor, and Critical thresholds.

Pie graphs are available only on attributes that have set thresholds. If the selected threshold does not exist for the attribute to graph, the system prompts you to create or choose another threshold. If the threshold is unavailable after graph creation, a no data image appears for the pie chart even if there is data in the database. This is because, data is reported based on the context of a specific threshold and the breakdown of data points into five different discreet ranges is determined by the threshold value. 

Pie graphs offer a 3D option (available only through the Operations Console), and can be added to a view.

Pie graphs allow users to see compliance to threshold over a period, and simultaneously see the percentage time where data is falling into each range of values. This kind of graph makes most sense in a view that updates automatically (on a daily basis).

To create a pie 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 Pie Graph option Pie_graph.gif.
  4. Select the Group Filter.
  5. Select the Monitor Type. You cannot select more than one monitor type here.
  6. Click Next.

    The system populates the corresponding attributes in the lower pane.
  7. Select a single Attribute, and click Apply.
  8. Make your selections on the Custom Graph screen.

  9. Click Generate Graph.
    You can change the parameters here, or use the icons located on the side of the graph to perform other functions. For more information about these icons, see Additional-information-for-changing-graph-display.

    Note

    • The Forward and Backward buttons that help you view graphs corresponding to the succeeding and preceding time range, respectively, are not available for pie graphs.
    • Although the breakdown is described in terms of percentage ranges, values in the graph are shown in terms of the unit that it is collected.
