Solution
The reason the user is seeing gaps in the execution profile is due to how the data collection is set up in the tool. By default,
Process Model execution threads are not included in the captured or displayed data.
You can enable the
Process Model execution threads logging by navigating to
File >>
Configure Data Collection to launch the
Configure Data Collection window.

Make sure that the checkbox for
Process Model is ticked.

After that, you need to navigate to
View and make sure
Show Process Model is checked so that the
Process Model execution threads will be shown.

After changing the settings as above, you will see more details on the TestStand Execution Profiler.
