Data source error when checking reports web UI vtune profiler

karanveer23 · ‎08-06-2021

Hey Guys

Running web UI for profiler , runs fine but when click on any report , its hangs on generating data

[root@node1 bin64]# ./vtune-backend --web-port=8080 --allow-remote-ui

Below are the errors from cmd line

[root@node1 bin64]# ./vtune-backend --web-port=8080 --allow-remote-ui
No TLS certificate was provided as a --tls-certificate command-line argument thus a self-signed certificate is generated to enable secure HTTPS transport for the web server: /root/.intel/vtune/settings/certificates/middleware.crt.

Can you please provide more detailed scenario. Are you trying to open a precollected result in browser?

Please also elaborate on the hang on generating data - how does it look like? Probably the screenshot would help.

Thanks,

Alyona.

- Trying to open from other systems using browser

- When 2 or more users trying to open reports using browser

Hi,

I see that the data finalization completed once on Aug 05, 18:54:19 - were you able to view the result after that? Do the results appear after a hang?

karanveer23 · ‎08-10-2021

Hi,

Check below latest screenshot , its stuck at finalizing the results . I got the results few hrs back , that time i was able to see the report and now its stuck at this screen. This shot has been taken from Vtune server using vtune-gui . The localhost is not able to process the results , its strange.

Hi,

Sorry for the late reply. We tried running vtune-backend and we didn't get any error.We tried in oneapi devcloud with vtune 2021.6.0.If you are still not able to connect through web server make sure you have tried these steps:

1)Go to the path 'vtune/latest/bin64/'

2)Execute the command 'vtune-backend --web-port=8080 '

3)After this URL will be generated. Do the tunneling steps if required.

4)Open the URL from browser.

5)If you are trying it for the first time you will be asked for passphrase.

6)After this VTune profiler will be opened and you can proceed with the analysis.

Please find the below link for reference :

https://software.intel.com/content/www/us/en/develop/documentation/vtune-help/top/launch/web-server-ui.html

Could you please share with us the results folder and the configuration snapshot of the analysis you are running in the VTune GUI in local host?

Thanks and Regards

Rahul
