System Reporter 2.8

5.3.4.3 Compare

This control is only valid for some Versus Time performance reports and the options available depend on the report. If the none option is selected, the aggregate performance metrics of the selected systems and objects are presented versus time. However, instead of the aggregate

--if you want to compare systems or objects -- select the appropriate Compare option. For example, if the System option is selected, the performance metrics for each selected system are plotted separately. An example of this is shown in Figure 5-7. Versus Time with Compare=System Report Example on page 5.21.

The number of objects that can be compared in a report is limited to 16 (the number of distinct colors available for charts). With some reports, if there are more than 16 objects present then the Select Peak control (see section 5.3.4.4 Select Peak on page 5.25) can be used to select 16 objects to compare.

5.3.4.4 Select Peak

For some reports, when the number of objects to be compared (see section 5.3.4.3 Compare on page 5.25) exceeds 16, the Select Peak control can be used to select which 16 objects to compare. The Select Peak control is used to select a metric (for example, total_iops) and the 16 objects that have the highest peak in the selected metric in the selected time range are chosen.

5.3.4.5 Group By

This control is only valid for At Time reports and specifies the X (category) axis for the reports. The menu options available depend on the report selected and are listed with each report. One or more Group By options can be selected (use CTRL+CLICK to select multiple options) and the default if none are selected is System. There is an X axis value for (and/or a table row for) each unique combination of selected objects that exists in the data table. For example, if System and Host in the Group By options are selected for the VLUN performance report, a table row and chart X axis value exists in the report for each System:Host combination that exists in the VLUN data table as shown in Figure 5-8. Group By System:Host At Time Report Example on page 5.22. See Table 5-7for a listing of all available options.
