For example, a typical Intel Haswell CPU has 164 PMCs whereas Intel Skylake processors have 385 PMCs. The following are some of the significant properties of PMCs. PMCs have been developed primarily to aid low-level performance analysis and tuning.
as well as micro-architectural events originating from the processor and its performance monitoring unit called the hardware events such as cache misses, branch instructions, etc. They include software events, which are pure kernel-level counters such as page faults, context switches, etc. Performance events or performance monitoring counters (PMCs) are special-purpose registers provided in modern microprocessors to store the counts of software and hardware activities. Furthermore, we explore the standard tools to collect utilization metrics for the execution of applications in Linux. In this post, I explain the standard tools to collect performance monitoring tools in modern computing platforms.
