The uncore performance monitoring units (uncore PMUs) provide many useful information like memory controller traffic, traffic between sockets/processor packages, energy related metrics in the uncore (sleep states for Intel® Quick Path Interconnect links or DRAM sleep states for example). These metrics can be used in tools for system and platform analysis.
The documentation for uncore performance monitoring units for various Intel processors is distributed over different documents. In this blog I will try to summarize the links to the corresponding documents that should help searching for the correct document.
|Intel® Core™||various||memory traffic, last level cache (CBO) events in SDM (chapter 18 Performance Monitoring)|
|Intel® Xeon® 5500 and 5600 series||Nehalem-EP and Westmere-EP||SDM (Chapter 18 Performance Monitoring, Sections 18.7.2 and 18.8 accordingly) and this guide|
|Intel® Xeon® 7500 series||Nehalem-EX||this uncore PMU guide|
|Intel® Xeon® E5 series||SandyBridge-EP (Ivytown-EP)||this uncore PMU guide|
|Intel® Xeon® E7 series||Westmere-EX||this uncore PMU guide|
|Intel® Xeon® E5 v2 and E7 v2 series||Ivybridge-EP and Ivybridge-EX||this uncore PMU guide|
|Intel® Xeon® E5 and E7 v3 series||Haswell-EP and Haswell-EX||this uncore PMU guide|
|Intel® Xeon® D-1500 series||Broadwell-DE||this uncore PMU guide|
I hope this summary can help you.
