Figure 5-7. Versus Time with Compare=System Report Example
If you want to compare the performance of a particular class of objects (for example, systems),
then you can use the Compare control (see section 5.3.4.3 Compare on page 5.25) available in
some reports if the Report Type is Versus Time. Figure 5-7. Versus Time with
Compare=System Report Example shows an example where systems are being compared. In
this kind of report, for each metric there is a single line per object being compared so it is not
possible to break down components (for example Reads and Writes) of the metric.
