Hi Stephane, Thanks for the fix. The fix helped quite a bit: $ sudo ./syst_smpl -e instructions:period=1000000 -G machine.slice/machine-qemu\\x2drawhide\\x2dx86_64.scope instructions:period=1000000 period=1000000 freq=0 monitoring on CPU7, session ending in 10s syst_count sets up counters on each of the processors. Shouldn't syst_smpl be setting up sampling on each of the processors rather than just one? -Will > > > On Mon, Jan 26, 2015 at 9:01 AM, William Cohen <wco...@redhat.com> wrote: >> On 01/26/2015 11:11 AM, Stephane Eranian wrote: >>> On Tue, Jan 20, 2015 at 7:55 PM, William Cohen <wco...@redhat.com> wrote: >>>> I have been experimenting with the libpfm4 perf_example syst_smpl.c >>>> and syst_count.c on a fedora 21.
