Comparing Data Between Two Cards

MindStudio Insight allows developers to compare the operator performance between two cards to intuitively view the differences between them. For details about how to set baseline data and comparison data, see Data Comparison.

In card comparison mode, the Operator page does not display the duration percentage pie chart. Only the operator details table is displayed. The value of Rank ID is fixed and cannot be switched. Group By can be selected as required. Top N data records can be displayed.

The operator details table displays the difference between two cards. You can click See more in the Details column to view the baseline data and comparison data details, as shown in Figure 6. For details about the fields, see the field description corresponding to each value of Group By. The following figure shows the data comparison details when Group By is set to Computing Operator Type.
