Microsoft Windows has the tasklist command and the graphical Task Manager utility. IBM AIX has an updating running processes list as part of the topas and topas_nmon commands. The load average numbers in Linux refers to the sum of the number of processes waiting in the run-queue plus the number currently executing.
iostat does not display information about the individual volumes on each disk if a volume manager is used . The vxstat command can be used to show this information instead. [1] In contrast, when using Linux LVM as a volume manager, iostat does display volume information individually, because each logical volume has its own device mapper (dm ...
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 ...
%CPU: How much of the CPU the process is using %MEM: How much memory the process is using ADDR: Memory address of the process C or CP: CPU usage and scheduling information COMMAND* Name of the process, including arguments, if any NI: nice value F: Flags PID: Process ID number PPID: ID number of the process's parent process PRI: Priority of the ...
– Linux User Commands Manual: reports individual or combined processor related statistics. – Linux User Commands Manual: reports statistics for Linux tasks (processes) : I/O, CPU, memory, etc. – Linux User Commands Manual: reports input/output statistics for network filesystems (NFS).
Linux is a Unix-like computer operating system assembled under the model of free and open-source software development and distribution. Most Linux distributions , as collections of software based around the Linux kernel and often around a package management system , provide complete LAMP setups through their packages.
cgroups (abbreviated from control groups) is a Linux kernel feature that limits, accounts for, and isolates the resource usage (CPU, memory, disk I/O, etc. [1]) of a collection of processes. Engineers at Google started the work on this feature in 2006 under the name "process containers". [ 2 ]
This is a list of commands from the GNU Core Utilities for Unix environments. These commands can be found on Unix operating systems and most Unix-like operating systems. GNU Core Utilities include basic file, shell and text manipulation utilities. Coreutils includes all of the basic command-line tools that are expected in a POSIX system.
