Intel Processor Events Reference

Intel® VTune™ Amplifier provides a set of hardware event-based analysis types that help you estimate how effectively your application uses hardware resources. These analysis types monitor hardware events supported by your system's Performance Monitoring Unit (PMU). The PMU is hardware built inside a processor to measure its performance parameters such as instruction cycles, cache hits, cache misses, branch misses and many others.
