Arm MAP, a performance profiler supporting Linux platforms.; AppDynamics, an application performance management solution [buzzword] for C/C++ applications via SDK.; AQtime Pro, a performance profiler and memory allocation debugger that can be integrated into Microsoft Visual Studio, and Embarcadero RAD Studio, or can run as a stand-alone application.
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 ]
%Cpu(s) counts the percentage of CPU usage, broken down into categories. MiB Mem: Memory usage in units of mebibyte. The buff/cache is for memory used by buffers and cache. MiB Swap: Swap space usage in units of mebibyte. If the system needs more memory resources and the RAM is full, inactive pages in memory are moved to the swap space.
– 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).
(For example, the "e" or "-e" option will display environment variables.) On such systems, ps commonly runs with the non-standard options aux , where "a" lists all processes on a terminal , including those of other users, "x" lists all processes without controlling terminals and "u" adds a column for the controlling user for each process.
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]
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.
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.
