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

[sandy4gr]

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

Sandeep,

Normally that error message does not mean something is broken, it means simply that in fact the events that you're sampling for have not occurred in statistically signifant numbers. That said:

1) Try running the vtl experiment with the default sampling events, clockticks and instructions retired. Do you see an error? If not, try adding some secondary events of interest and note the vtune response.

2) If you are certain you want to use the specific events that you have already put in the vtl command: is calibration turned off? If so, turn it on and compare results. (Note that your application will run at least twice with calibration turned on: this is normal).

cheers
