VTune collection stops prematurely

Hi,

I am trying to use VTune's "System Overview" to find the cause of a 6ms delay in my real-time application, by looking for unexpected context switches. I want to let the tool run overnight, and stop the collection when the delay is detected. I have instrumented my code to call __itt_detach() when the delay is detected (from the ITT API). However, the collection stops after about 4 minutes without my trigger condition ever being hit. How can I set up VTune to collect continuously until __itt_detach() is called?

Thanks,
Mike

I found the setting I needed; there is "Limit collected data by:" in the "WHAT" pane; I need to select "Time from collection end" instead of "Result size".
