On-Demand Report Options

When you create an on-demand report template, multiple options let you select the number and appearance of charts in the generated report.

View Options determine how the on-demand report displays data. As you configure the report, you can select multiple items or a single group for reporting. View options determine how charts represent all metric families that you select, from all of the selected managed items or groups. Group rollup data is represented by aggregated trend lines.

The following options are available:

• Chart with Multiple Metrics: This view consists of one chart that displays a trend line for each metric that you selected. Different colors are used to distinguish the trend lines.
• Chart per Metric: This view consists of one chart for each metric that you selected. Each chart displays a trend line for the metric.
• Chart per Item with Multiple Metrics: This view consists of one chart for each item or group that you selected. Each chart then displays trend lines for every metric that you selected.

  Some metric families automatically report on multiple device components. For example, a CPU metric family reports data from all CPUs that are detected on a managed device. In these cases, a separate chart is created for each CPU.

• Chart per Metric with Multiple Items: This view consists of one chart for each metric that you selected. Each chart then displays trend lines for each item or group that you selected.

  Note: Groups are represented as individual items for reporting. The data is rolled up from all managed items in each group.

Take care to select managed items and metric families that complement each other. After you make initial selections, changing the item context can clear the original selections. For example, if you select three routers for reporting and then add interfaces, the routers are cleared. The report reflects interface data, but no rollups to the router level.

Other device types and components are compatible for reporting in a single on-demand report, however. For example, routers and servers can be included in the same report.

Also keep in mind the amount of processing that is required for certain combinations of options. Groups with a large number of managed items require a great deal of processing, particularly if you then select an option that requires a chart for each item. This situation is exacerbated when you also select component metrics for reporting, such as CPU or memory. For example, you are reporting on a group that contains 200 routers, and you select 'Chart per Item with Multiple Metrics' as the View Type. If you then select CPU metrics from the list of Metrics to Include and change the 'Metric Calculate Level' to ‘by Component,’ , the view sends queries to Data Aggregator for CPU data from every CPU in every router in this group. And then 200 charts must be rendered for the report to be fully generated.
