How to count stalls in MIC using vtune

I am using Vtune for MIC and would like to know which event should be considered for counting the number of cycles where no micro-operations is issued, i.e. thread idle time due to un-available resource.

Is it correct if we use FE_Stalled, to count the thread idle time due to un-available resource, which appears in PMU, revision 1.01, July 10, 2012, Doc. 327357-001!

Asked (by the same respondent) and answered in the Intel Xeon Phi coprocessor forum.  To recap, probably as close as you're going to come to what you want, but be careful to understand what it gives you before you begin to rely on it.
