Trying to collect a Memory Consumption snapshot of my application on Linux. I downloaded and installed Vtune today. But starting the application from VTune for the Memory Consumption profile immediately fails after launch and VTune reports:
"Cannot open data: Intel opeAPI VTune Profiler 2021.4.0 has faced a serious problem.
Error 0x40000024 (no data)... "
The target application doesn't even properly start (no window). I can successfully collect Memory Access or Performance Snapshot capture of the application though. I can also collect a Memory Consumption capture of a VTune sample (matrix) app that's included.
I built and installed sampling drivers, vtune-self-checker output looks good too. I can provide you with actual logs over email (not public forum).
Help is appreciated.

Thank you for reaching out. Inorder to understand the issue please share with us the following details:
1. complete output from the command line
2. VTune result folder (if available)
3. The self-checker output.
If you do not want to share these details in the forum, we will connect to you privately.
Apologies for the silence, I was on vacation and then I wanted to give debugging the issue a shot first before sharing a repro with you since it's our app crashing/failing to initialize when run under VTune's Memory Consumption capture. That investigation lead to no obvious culprits. I unblocked myself getting system memory usage data using WPR on Windows and don't need to run this profile on Linux at this time anymore. I also don't have an easy way of providing you with a minimalistic repro you asked for or even a full application package drop.
Thank you for the prompt assistance, and we may reach out when we need to use VTune's Memory Consumption profile on Linux again.
Thank you for the update. We are closing the query for now. If you need any additional information, please submit a new question as this thread will no longer be monitored. Please reach out to us in case of any issues.
