Sampling Collector start failure
Hi,
I have tried to start the Sampling Collector configuration from my "Intel(R) VTune(TM) Performance Analyzer
9.0" but I have received an Error: unable to create environment file "./environment.xml" on hostname(ip)[ERROR] The
Sampling Collector failed to start because the driver is not loaded now!
I have checked the driver
(/vtune_drv-x32-2.6.18-128.1.6.el5PAEsmp.ko) that it matches the kernel (Linux ucdev 2.6.18-128.1.6.el5PAE #1 SMP Tue
Mar 24 12:39:24 EDT 2009 i686 i686 i386 GNU/Linux) on my server machine and that it installed properly:
[root@ucdev vdk]# lsmod | grep vtune
vtune_drv 200748 0
Everything looks ok but still refuses to
work.
Please advise.

Re: Sampling Collector start failure
On the face of it, you may have to return (as root) to the directory where the driver exists, and run ./insmod-vtune.
In my experience, wheh you build a driver in vdk/src, you must copy it to vdk in order for vtune to restart
automatically on reboot.
Also, check that youhave write permission in your current directory, or in the directory
which you specified should be current during the sampling run.

I suggest to check:
1) If this was not caused by vtune driver, please run vtl - "vtl activity -c sampling -d
10 run". If you are using "root" user, there should be an environment.xml file under
/root/VTune/Projects.
2) Try vtlec with "root" user, if you use default workspace under
/root, vtwrkspc.vws should be created under /root, and environment.xml should be under
/root/Project1/.vtproject.data. If you can't see this, I suspect a) You may have
write-permission problem to create xml file, or b) vtwrkspc.vws is destroyed. As a workaround, you can use other
folder as workspace, or delete destroyed vtwrkspc.vws manually and redo.
3) Is it possible that you can
copy workable environment.xml to /root/Project1/.vtproject.data?

Hi Peter,
I'm not using "root" user but I have checked your sugestions in my environment. First of all I
didn't find any "vtl" to run.
Second because that I'm not a "root" user my environment.xml located under
/opt/intel/vtune/rdc/global_data/vtserver_blansky/ and I don't have any *.vws file. I do have
"Project.Master.Linux.Remote" file under the same /opt/intel/vtune/rdc/global_data/vtserver_blansky/ directory. So the
question is if the files that I have are enough or I should have the structure that you have described above (and if yes
what should I do to create the similar environment)?

Hi,
I also have the same problem (I'm working with blansky), it seems that there are no permisions to none
root user to activate the sampling (with root user everything works). How can I change the permissions so a regular user
will be able to run the sampling project?
Thanks,
Dan

It seems that you are using sampling remote data collector on Linux* side ONLY, so you can't find vtl & vtlec.
.vws file is not required for remote data collection.
It is good that you have environment.xml under
proper directory. I saw that you have vtune drived loaded...can you check if your user account is in "vtune" group?
By the way, VTune(TM) Analyzer v9.0 is too old - can you please use lastet v9.1 Update 2?
Regards,
Peter
