vtune -collect platform-profiler Error: An unexpected error has occurred.

侯玉山 — Fri, 15 Oct 2021 02:11:19 GMT

Hello, I encountered such an error when executing VTune - collect platform profiler

This is the command I execute on the command line:

[root@c1 latest]# vtune -collect platform-profiler -data-limit=20 --duration 60 -r ./01platform_profiler
Warning: PMU counter(s) [GP0 ] is/are already in use by other software and the data collected on these counter(s) may be incorrect
vtune: Collection started. To stop the collection, either press CTRL-C or enter from another console window: vtune -r ./01platform_profiler -command stop.
vtune: Error: An unexpected error has occurred. Our apologies for this inconvenience. Please gather a description of the steps leading up to the problem and contact Intel customer support.
vtune: Collection detached.
vtune: Collection stopped.
vtune: Platform Profiler report is not available from the command line. To view the result, use VTune Profiler Graphical Interface.

And when I changed to VPP collect start collection, I encountered this problem：

[root@c2 collector]# vpp-collect start -d ./1015_vpp_dir

I installed PCP according to the log, but I found that the PCP module can not be installed simply. I don't know why.

thanks for your help.

Could you please share your OS details and the VTune version?

We are able to reproduce the issue "vtune: Error: An unexpected error has occurred" using VTune version 2021.8 in Ubuntu 18.04.

hi,

Through your support, the previous problems have been solved and the collection can run successfully. However, when I view the collection results, I can't see the collected data.

Then I use the VPP collect start command to collect. After collection, I check the vpp-collect.log file and report this error:

ipmwatch: error while loading shared libraries: libsafec-3.3.so.3: cannot open shared object file: No such file or directory

Is this "libsafe-3.3. So. 3" dependent on a module of oneapi, Can I import from a module.

thank you

Hi,

Could you please share the result folder and the complete log file?

Also share the sample reproducer and the exact steps to reproduce this error.

Thanks.

Hi,

I used the following steps to perform the collection:

module load vtune/2021.8.0-nda

source vtune/2021.8.0-nda/vpp/collecter/vpp-collect-vars.sh

vpp-collect start -c "comment" -d /data/test_for_vtune_dir/1026_vpp-collect_dir/

Output on the command line:

[root@c1 collector]# vpp-collect start -c "comment" -d /data/test_for_vtune_dir/1026_vpp-collect_dir/

Hi,

Sorry, The last vpp-collect.log attachment is the log after collection. The current vpp-collect.log attachment is the log when collection starts.

Thanks.
