I need some help to get the number of cycles stalled due to load buffer full. The E5-2680 do not provide RESOURCE_STALLS.LB event. I want to know that if there are any other way to measure such cycles.
I believe that event should be supported on your processor. I think the E5-2680 is a Jaketown (Sandy Bridge Server). The list of supported event is here: https://download.01.org/perfmon/JKT/Jaketown_core_V18.json I see the event in the list. Can you let me know if that's not matching up with what you are seeing?
