offcore events in Xeon E5-2620 v3 is not supported

Hello

I'am trying to monitor the offcore events in Exon E5-4620, the kernel is 4.3.0, and the system is running normally.  After the system downtime, I reinstall the system. Now, when I run pmu-tools, the ocperf.py no longer support offcore. As follows. So, how to use offcore again, or what problem I have met?

failed to read counter offcore_response_demand_code_rd_llc_miss_remote_dram
# time        core cpus    counts                   unit events
0.100098644  S0-C0   1   <not supported> offcore_response_demand_code_rd_llc_miss_remote_dram

Thanks,

wang,
