Seems ITT task event in user application could not be tracking when on "profile system" selected,

[yidu]

Hi,

I'm trying to optimize my application's performance on a FreeBSD system. I've installed VTune 2024.2.0 on my Ubuntu laptop and I'm using remote SSH to analyze the performance. I successfully performed hotspot analysis using hardware event-based sampling.

I created a sample application with ITT API enabled, deployed it to a remote FreeBSD machine, and added the INTEL_LIBITTNOTIFY64 environment variable in the startup script. When I use the "Launch Application" feature with this startup script, everything works fine, and I can see the user task events in the results. However, when I use the "Profile System" feature to instrument and manually run the same script, I can't see these user events at all.

Is this behavior by design, or is there something wrong with my environment?
