Hi,

I'm trying to get number of L2 cache misses on a system level via:
  sudo pmcstat -S dc-misses -O /tmp/sample.out

However, I'm getting this error:
pmcstat: ERROR: Cannot allocate system-mode pmc with specification "dc- 
misses": Invalid argument

I'm running 7.1-RELEASE-p3 on:

What am I doing wrong?

Thanks,
