The Intel Processor Performance Monitor is a set of specialized diagnostic tools designed for monitoring raw hardware events, memory latency, PCIe throughput, and processor power states on Intel architecture.
The project provides dedicated utilities for measuring data throughput across sockets and PCIe buses, tracking power usage and sleep states to identify frequency throttling, and analyzing cache misses and memory access times. It also includes a hardware event profiler for querying raw core and uncore register events to monitor specific processor behaviors.
Capabilities cover comprehensive hardware performance analysis, including memory bandwidth across channels and ranks, thermal headroom, and the tracking of specialized hardware accelerators. The system supports custom hardware event programming via raw register encoding and provides a mechanism to export collected performance data via HTTP interfaces for integration with external monitoring systems.
