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?
