Failed to start intel Vtune for first time

[Gladyshev_mv]

Hello, everyone. 

I have some troubles to install application.

I'm successful download app and start sh script.

wget https://registrationcenter-download.intel.com/akdlm/IRC_NAS/4466ed1b-5d4a-4b30-9146-1eabc336c647/l_oneapi_vtune_p_2023.1.0.44286_offline.sh

sudo sh ./l_oneapi_vtune_p_2023.1.0.44286_offline.sh

and next, when I try to start gui app, i got white screen.

In console I see next logs:

next I start vtune-server and try to connect to it and got this:

After I try to start vtune-agent, I got this console output:

Hi, 

Thank you for posting in Intel communities.

>> I have some trouble installing the application. I'm successful download the app and start sh script. When I try to begin gui app, I got a white screen.

Are you trying to run Intel® VTune™ Profiler as a sudo user? If yes, it is not necessary to run Intel® VTune™ Profiler as a sudo user to get elevated profiling privileges.

You can add your username to the "vtune" group to provide sufficient privileges to Intel® VTune™ Profiler. This can be done using the below command:

sudo usermod -a -G vtune <username>

Reboot the system to check if the user has been added to the group by running the below command:

id <username> | grep vtune

Running Intel® VTune™ Profiler GUI as a super user/root user is disabled as a security feature/policy.

>> Next I started vtune-server and try to connect to it , but got an unexpected error.

VTune Profiler Agent is integrated into Intel® VTune™ Backend and more options are available in Intel® VTune™ Backend. 

So, you can use the Intel® VTune™ Backend (Web Server Interface) by running the below command:

sudo <vtune-install-dir>/bin64/vtune-backend --allow-remote-ui

Eg.:

sudo /opt/intel/oneapi/vtune/latest/bin64/vtune-backend --allow-remote-access

An URL will be generated which can be opened in your browser. The first time you access this URL, you will be shown a warning regarding a self-signed certificate since the website is loaded locally, kindly confirm and bypass this warning to access the Intel® VTune™ Backend (Web Server Interface).

Refer to Intel® VTune™ Backend (Web Server Interface) Documentation

Thank you for help.

Yes, I start gui application as sudo - that is my fault.

I' am add my user to vtune:

robotech@ubuntu:/opt/intel/oneapi/vtune/2023.1.0/bin64$ id root | grep vtune
uid=0(root) gid=0(root) groups=0(root),1001(vtune)
robotech@ubuntu:/opt/intel/oneapi/vtune/2023.1.0/bin64$ id robotech | grep vtune
uid=1000(robotech) gid=1000(robotech) groups=1000(robotech),4(adm),24(cdrom),27(sudo),30(dip),46(plugdev),120(lpadmin),131(lxd),132(sambashare),1001(vtune)

but, when I try to attach to the process (witch run as root), I got this Error:

"Cannot find a running process with the specified ID or there are no permissions to access it. Provide a valid PID".

When I use console command as root, the snapshot gets right, but how I can do it from GUI?

sudo ./vtune -collect threading -target-pid 3635

Hi, 

Good day to you.

This is an expected behavior as you are running the program as a root user and opening the Vtune GUI as a normal user installed in your system as we can see from the screenshot.

It cannot access that process so the Vtune GUI will not work properly.

A possible workaround can be if you run an Intel® VTune™ Backend (Web Server Interface) by running the below command:

 sudo <vtune-install-dir>/bin64/vtune-backend --allow-remote-ui

Eg.: 

sudo /opt/intel/oneapi/vtune/latest/bin64/vtune-backend --allow-remote-access

An URL will be generated which can be opened in your browser. The first time you access this URL, you will be shown a warning regarding a self-signed certificate since the website is loaded locally, kindly confirm and bypass this warning to access the Intel® VTune™ Backend (Web Server Interface).

Thank you for help so much.

Can I ask one more question about agent ? 

It can not find automatic. If I download manually it works good, but maybe there is another way to do it?

SSH server is running

Hi,

Glad to know that your issue is resolved.

And regarding this doubt of yours.

>> Can I ask one more question about agent ? 

  It can not find automatic. If I download manually it works good, but maybe there is another way to do it?

Earlier it used to download automatically and now it doesn't happen the same. We have asked the development team about it and waiting for the reply.

We are working on this internally and will get back to you once we get an update from them.

Thanks and Regards,

We have checked with the development team and this is not the expected behavior for the VTune server. It should do auto-deployment. 

They confirmed that it is a bug and will be fixed in the next releases of VTune.

If this resolves your issue, make sure to accept this as a solution. 

This would help others with similar issues. Thank you!
