Several tools with combined sampling and call-graph profiling. A set of visualization tools, VCG tools, uses the Call Graph Drawing Interface (CGDI) to interface with gprof. Another visualization tool that interfaces with gprof is KProf. Free/open source - BSD version is part of 4.2BSD and GNU version is part of GNU Binutils (by GNU Project) HWPMC
The documentation of perf is not very detailed (as of 2014); for example, it does not document most events or explain their aliases (often external tools are used to get names and codes of events [15]). [16] Perf tools also cannot profile based on true wall-clock time., [16] something that has been addressed by the addition of off-CPU profiling.
The Linux version of top is part of the procps-ng group of tools. It was originally written by Roger Binns [4] and released in early 1992 but shortly thereafter taken over by others. [5] On Solaris, the roughly equivalent program is prstat. Microsoft Windows has the tasklist command and the graphical Task Manager utility.
It shows a frequently updated list of the processes running on a computer, normally ordered by the amount of CPU usage. Unlike top, htop provides a full list of processes running, instead of the top resource-consuming processes. htop uses color and gives visual information about processor, swap and memory status. htop can also display the ...
mpstat is a computer command-line software used in Unix-type operating systems to report (on the screen) processor-related statistics. It is used in computer monitoring in order to diagnose problems or to build statistics about a computer's CPU usage.
It is a multi-purpose benchmark that features tests for CPU, memory, I/O, and database performance testing. [3] It is a basic command line utility that offers a direct way to benchmark computer hardware. It now comes packaged in most major Linux distribution repositories such as Debian, Ubuntu, CentOS and Arch Linux. [4]
Additional to sar command, Linux sysstat package in Debian, [4] RedHat Enterprise Linux and SuSE provides additional reporting tools: : Collect, report, or save system activity information. – Linux User Commands Manual: Collect and store binary data in the system activity daily data file.
nice is a program found on Unix and Unix-like operating systems such as Linux. It directly maps to a kernel call of the same name. nice is used to invoke a utility or shell script with a particular CPU priority, thus giving the process more or less CPU time than other processes. A niceness of -20 is the lowest niceness, or highest priority.
