vtune resolve is looking in /tmp/amplxe-tmp-<host_uername> when files are in /tmp/amplxe-tmp-root

[jlarsen]

I am trying to profile a remote embedded linux target.

The target can only run as root.

When I run the vtune-gui application on my linux host system I run it as <host_username>.

After the vtune analysis, in the collection log tab, I get a bunch of error like these:

Cannot locate debugging information for file "/tmp/amplxe-tmp-<host_username>/modules.ssh_root@<ip>/<some_dir>

Is there some way to tell the host run vtune to use the target username (root in this case) when looking for these files?

Hi,

Thank you for posting in Intel Communities.

Can you please answer the following questions:

• Can you please tell me the name of the operating system and processor details you are using? (If Linux, please specify the distribution like Centos7,8, Ubuntu18,20, etc)
• Are you trying remote system profiling with Vtune? (If yes, please specify the host operating system and target operating system)
• You mentioned you ran Vtune analysis and observed some errors in the logs. If those are warnings, please ignore them. If possible, attach screenshots for our better understanding.
• Please attach self-checker logs by running the below command.

<Vtune_installation_directory\latest\bin64\vtune-self-checker.bat> for windows.

<Vtune_installation_directory\latest\bin64\vtune-self-checker.sh> for linux.

• If possible, attach a sample reproducer and screenshots. so we can reproduce your issue from our end.

Thanks,

Hi,

You want Vtune to look into this directory (/tmp/amplxe-tmp-root). With the help of the (-target-install-dir=/tmp/amplxe-tmp-root) flag, you can say vtune to look into a particular directory.

Please go through the below screenshot.

Cannot locate debugging information for file - This is a known warning. Please ignore that.

If this resolves your issue, make sure to accept this as a solution. This would help others with similar issues.

Thanks,
