It can be useful to compare session data in order
to understand the effect of differences in activity at different times
of day, week, or month. Comparisons can be especially useful when
running performance testing benchmarks. (See Preparing a Benchmark.)
To compare data files, do the following:
From the main console, open two data files of the
same type that you want to compare.
Two ways exist to create a combined set of comparable
data:
In one viewer, click FileCompare , or
click the Compare button .
The Compare window
opens, and you can now see the other file to compare your first file
against.
Click the file name that you want to compare against.
When the file is highlighted, click the Compare button.
A new profile viewer opens
that presents the selected data sets in comparison to one another.
NOTE: For alternate access when you have multiple viewers
open, click the button to bring the console to
the top. The console lists all open sessions and data sets. For data
sets, click the data representation to bring the already open viewer
to the top.
If the viewer has been closed, but the data representation
is still listed in the console, double-clicking the data representation
opens a new viewer.
