We are trying to use VTune for the first time and we are trying to use Event Based sampling. However we get the log message "The Sampling Collector failed to collect data because the selected event(s) did not occur.".
We run VTune (version 7.2, build 16929) on a Pentium III system (Family 6 Model 8 Stepping 6, 496MHz and 768 MB RAM) running "Windows Server 2003 Enterprise Edition" and we have only selected the "clockticks" and "instructions retired" events.
We get the error message regardless of which of the calibration radio-buttons is selected in the "Configure Sampling" dialog. We have a sampling interval setting of 1 millisecond and we sample for 20 seconds or more. We have tried to follow the "VTune Help Trouble Shooter", but with no success. :(
We have not changed any default settings for "Sample After" for any events, thus for the clockticks event we have a "Sample After" setting of 500000. VTune reports system bus frequency as 533MHz.
