ICACHE.MISSES Parameter on Xeon-E5

Hello,

I am using intel xeon E5-24xx machine. When I try to read the parameter ICACHE.MISSES, most of the applications are reporting its values as 0. If I am not mistaken it is the Instruction cache misses of L1. 

Please give me any idea how to check why this parameter is giving 0 value.

Regards
