Free/open source - BSD version is part of 4.2BSD and GNU version is part of GNU Binutils (by GNU Project) HWPMC: FreeBSD 6.0+ System-level and process-level counting and sampling hardware performance monitoring framework supporting multiple architectures. BSD Instana: Linux, Windows, iOS, Android, Azure, AWS, AIX, Solaris, HP/UX, zOS, zLinux
It supports hardware performance counters, tracepoints, software performance counters (e.g. hrtimer), and dynamic probes (for example, kprobes or uprobes). [4] In 2012, two IBM engineers recognized perf (along with OProfile ) as one of the two most commonly used performance counter profiling tools on Linux.
nmon (Nigel's Monitor [2]) is a computer performance system monitor tool for the AIX and Linux operating systems. [3] [4] The nmon tool has two modes a) displays the performance stats on-screen in a condensed format or b) the same stats are saved to a comma-separated values (CSV) data file for later graphing and analysis to aid the understanding of computer resource use, tuning options and ...
Operating system support for accessing hardware counters is needed to use PAPI. For example, prior to 2010, a Linux/x86 kernel had to be patched with a performance monitoring counters driver (perfctr link) to support PAPI. Since Linux version 2.6.32, and PAPI 2010 releases, PAPI can leverage the existing perf subsystem in Linux, and thus does ...
Ganglia software is bundled with enterprise-level Linux distributions such as Red Hat Enterprise Linux (RHEL) or the CentOS repackaging of the same. Ganglia grew out of requirements for monitoring systems by Berkeley (University of California) but now sees use by commercial and educational organisations such as Cray, MIT, NASA and Twitter.
Cacti is an open-source, web-based network monitoring, performance, fault and configuration management framework designed as a front-end application for the open-source, industry-standard data logging tool RRDtool. [3] Cacti allows a user to poll services at predetermined intervals and graph the resulting data. Through the use of Cacti plugins ...
Called regularly by cron, sadc does the monitoring and stores its measurements to files in the /var/log/sa/ folder. The sar client can be used to explore this data. System Activity Report ( sar ) is a Unix System V -derived system monitor command used to report on various system loads, including CPU activity, memory/paging, interrupts, device ...
Phoronix is a technology website that offers information on the development of the Linux kernel, product reviews, interviews, and news regarding free and open-source software by monitoring the Linux kernel mailing list or interviews. Phoronix was started in June 2004 by Michael Larabel, who currently serves as the owner and editor-in-chief.
