Cannot see processes names and paths on sampling results

Edson_Borin__Intel_ — Wed, 05 Mar 2008 18:43:57 GMT

I cannot see the processes names and paths when viewing the results:

I created and run the following sampling activity:

vtl activity MispredictionPenalty-OO-2 -d 100000 -c sampling -o "-sterm yes -ec en=RESOURCE_STALLS.BR_MISS_CLEAR en=CPU_CLK_UNHALTED.CORE" -app ./perlbmk_peak.lnx32-icc-91-fast-g,"-I. -I./lib makerand.pl > makerand.out 2> makerand.err" -moi ./perlbmk_peak.lnx32-icc-91-fast-g run

when I view the results I only get the process name and the process path for the kernel module (vmlinux-2.6.18-1.2798.fc6). How can I get the process name and paths for the other processes, including the application that I'm interested in.

I appreciate any help.

If you don't have options other than the RVA view, make sure that your compilation uses -g both for building objects and for linking. If you still have problems, try PTU (see WhatIf forum).

Thanks for the quick answer Tim, I had compiled with -g option, but I'm sure it is not the problem, because even the example that comes with vtune does not show the processes names and paths.

What is PTU, and where can I find the WhatIf forum?

Thanks again

I run:

$ vtl activity -c sampling -app /opt/intel/vtune/samples/vtunedemo/vtunedemo -moi vtunedemo run

Then:

I find I must run insmod-vtune after each reboot, and rebuild vtune driver after each kernel update. PTU shares license and VTune driver with a recent VTune version.

Thanks Tim, I apreciate your help. I re-compiled the module and reloaded (had to reboot), now it shows the process names and paths.
