Developer API Documentation for Intel® Performance Counter Monitor

 

The Intel® Performance Counter Monitor (Intel® PCM: www.intel.com/software/pcm) is an open-source tool set based on an API. This API can be used directly by developers in their software. Besides the API usage example in the article, other samples of code using the API can be found in pcm.cpp, pcm-tsx.cpp, pcm-power.cpp, pcm-memory.cpp and other sample tools contained in Intel PCM package.

Intel PCM Column Names Decoder Ring

When Intel Performance Counter Monitor (Intel PCM) is generating csv files as output, short names are used as column headers. This helps to keep the table width at a manageable size if the data is loaded in a spreadsheet program. However, it makes it rather hard to guess what exactly is hiding behind these abbreviations.

Documentation for uncore performance monitoring units

Hello everyone,

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.
