sample collector failed to collect data because the selected event(s) doesnot occur

I am running Vtune 3.0 for linux on fedora core 1
I am using the vtlec for EBS data collection
It was running all fine until a while ago
where it started displaying error messages
"sample collector failed to collect data because the selected event(s) doesnot occur"
for 9 of the Events i selected
i have a program which runs for 15 mins

what gone wrong

Moderator, I hope a quick reply

Thanks

Callgraph profiling with custom setjmp/longjmp functions

I'm profiling a program on Windows that implements custom routines that do effectively the same thing as setjmp/longjmp. Callgraph profiling doesn't work at all in this case. The first longjmp results in a crash. Is this to be expected? Is there some way to workaround this issue?

I'm guessing that VTune recognizes the OS setjmp/longjmp and has special handling.

Instructions retired per function through command line

Hi,
I am trying to get the total no of Instructions retired for my program t.bat by running vtune through command line.
I tried with sampling option as " vtl activity -d 100 -c sampling -app t.bat -moit.bat run"
vtl views a1::r1 gives me total no of Instructions retired for t.bat
But I need it function wise (executed)

I tried to execute Call Graph as "vtl activity -c Call Graph -app t.bat -moi t.bat run", it failed saying Invalid data collector where as vtl query -lc shows Call Graph as valid data collector.
