The sampling of the basic events
CPU_CLK_UNHALTED.CORE
INST_RETIRED.ANY
fails with the "fisrt use" activity on the default vtunedemo
Failed to create sampling data base. Probably .tb5 files are corrupted or don't exist." "The Sampling Collector failed to collect data because the selected event(s) did not occur."
Interestingly sampling other events does work on Debian 5 e.g. INST_RETIRED.ANY_P
When I try this on Fedora 10 on the exact same PC everything works. Our company uses Debian 5 so I would really like to get this working under that OS.
Any help is greatly appreciated.
Thanks,
Adam

Could you please provide the following information:
Are you using a 32 or 64 bit OS?
What version of Eclipse are you using?
Most importantly, do you have the latest version of VTune (Update 7)?
Thanks,
Jackson

Just to double check, you aren't using a Virtual Machine at all, correct?
Thanks.

Okay thanks.
Could it be that you are using a Xen-enabled kernel? This is not supported. For more information see this link: http://software.intel.com/en-us/articles/does-vtune-analyzer-work-with-xen-enabled-kernels/
Could you look in /boot/config-`uname -r` . If there is a "CONFIG_XEN=y" and/or "CONFIG_X86_XEN=y" entry, then that kernel is Xen-enabled.
Also, is your Eclipse a 32 or 64 bit version?
Thanks.

It is the 64-bit version of eclipse.
No CONFIG_X86_XEN entry exists in the /boot/config-`uname -r` file

Ok thanks. I think this is the issue.According to the Release Notes:
"The VTune Analyzer 9.1 for Linux* can be integrated only with the 32 bit version of Eclipse 3.2.1 on Intel 64 systems. Integration into a 64-bit version of Eclipse is not supported."
If youare able to try a32-bit version of Eclipse you mayhave more success.
Thanks,
Jackson

Just to be extra cautious, you mention"No CONFIG_X86_XEN entry exists in the /boot/config-`uname -r` file". Does this go for "CONFIG_XEN=y" as well. If so, I will take this thread private to get some more information from you.
Thanks,
Jackson

Yes no XEN as far as I can tell.
I ran this:
>cat /boot/config-2.6.26-2-amd64 | grep -i "XEN"
CONFIG_NETXEN_NIC=m
