L1, L2 and LLC instruction and data cache misses on E5-2420 using intel vtune

Hi, 

I am trying to find out the L1, L2 and LLC instruction and data cache misses of the application. I am using Intel(R) Xeon(R) CPU E5-2420 0 @ 1.90GHz. Can you please tell me how can I find instruction and data misses using intel vtune. 

Secondly, if machine has hyper-threading active, should it be a good idea to turn it off to characterize the  application.

Regards,
