System Options dialog box: Profiling tab
Description
Initiates the logging of selected activities to a trace file
during the running of your entire application in the PowerBuilder
development environment.
Dialog options
Enable Tracing
Turn tracing on. This option is disabled when you restart PowerBuilder
or change to a different application.
Prompt for Override
Check this box if you want PowerBuilder to prompt you before
overwriting an existing trace file.
Trace File Name
A name identifying the trace file that will be generated from
the running application. The default is the name of the PowerBuilder library
that contains the application with the suffix .PBP for PowerBuilder profile.
Trace Label
A phrase or sentence identifying the tracing blocks in your
trace file. If you don’t provide a value for the label,
an empty string is placed in the trace file.
Timer Kind
A value that identifies the kind of timing information you
want included in the trace file.

The default timer used to record when each activity begins
and ends is the wall clock timer. The clock timer measures an absolute
time with reference to an external activity, such as the computer’s
startup time. The clock timer measures time in microseconds and,
depending on the speed of your computer’s central processing
unit, it can offer a resolution of less than one microsecond. The process
and thread timers measure time in microseconds with reference to when
the process or thread being executed started. Use the thread timer
for distributed applications. Both the process and thread timers
give you a more accurate measurement of how long the process or
thread is taking to execute, but both have a lower resolution than
the clock timer.
Trace Activities
Values identifying the application activities you want logged
to the trace file.
