In-Depth Information
To save a run, select File⇒Save As from the Instruments menu. The current run is saved to a
.trace
file, with
all the current settings and data. You can reload a trace with File⇒Open. After loading, you can record further
runs. They're added to the data in the usual way. The original runs aren't deleted or modified. You can then
resave the new file with a new name or overwrite the original.
Working with Instruments and Templates
You can use the templates to get started with Instruments. But to customize the testing with your own preferred
mix of instruments, you must understand the difference between instruments, documents, and templates.
Understanding templates
The standard templates have three elements:
One or more instruments
Default settings for each instrument
An appealing graphic that appears in the standard template list on launch
The default templates are designed to create a selection of standard useful profiles. But you can create custom
templates, with your own selection of instruments and settings. When you save a template, it's added to the
user library. You can select one of the standard icons for the template when you save it.
Creating a template
To create a new template, select File⇒New in Instruments and select the Blank template. Click the Library but-
ton, and drag and drop one or more instruments from the list onto the Instruments column at the left of the In-
struments window, as shown in Figure 16.26.
Go through each instrument, and change the settings to useful defaults. You can add multiple copies of the
same instrument to the template with different settings. For example, you might add two copies of the CPU
Monitor instrument and use the Configure options to display two different statistics in the time line, such as
PhysicalMemoryUsed and PhysicalMemoryFree.
CAUTION
Make sure you select only the instruments that match your target platform.
