|- System DRAM Read Throughput(MB/s): 4.99 -| ![]() |- Memory Channel Monitoring -||- Memory Channel Monitoring -| The following will collect three samples every second and exit. $ sudo -preserve-env=DESTDIR make installĬonfirm PCM is working by running pcm-memory. You can override this, say to /usr/local, or /opt, by setting the DESTDIR environment variable // Install to /usr (default) First, we need to create a directory to work in: $ mkdir ~/downloadsīy default, pcm will install to /usr. Build PCM from Sourceīuilding the PCM utility from source is very simple. PCM can be built from source or installed using the RPM or DEB files available for RHEL, CentOS, Ubuntu, Debian, SLE, and openSUSE. This article will focus on the pcm-sensor-server which is a pcm collector exposing metrics over http in JSON or Prometheus (exporter text based) format. PCM provides a number of command-line utilities for real-time monitoring. PCM works on Linux, Windows, Mac OS X, FreeBSD and DragonFlyBSD operating systems. It can also show memory bandwidth for DRAM and Intel Optane Persistent Memory devices. ![]() Processor Counter Monitor is an application programming interface (API) and a set of tools based on the API to monitor performance and energy metrics of Intel® Core™, Xeon®, Atom™ and Xeon Phi™ processors. This article demonstrates how to use the open-source Process Counter Monitor (PCM) utility to collect DRAM and Intel® Optane™ Persistent Memory statistics, and visualize the data in Grafana. In a previous article, I showed How To Install Prometheus and Grafana on Fedora Server.
