Problems with QPI statistics on IvyBridge

Hi,

We are facing problems with QPI statistics on IvyBridge.

When we run pcm.x, QPI statistics shows all 0 values. But other values (like processor type, per socket energy etc) shows up correctly.

Can you please suggest what could be done?

Regards,

Might it be that you are running two instances of Intel PCM?
