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.

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.
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]
iperf, Iperf, or iPerf, is a tool for network performance measurement and tuning. It is a cross-platform tool that can produce standardized performance measurements for any network. iperf has client and server functionality, and can create data streams to measure the throughput between the two ends in one or both directions.

In computer science, Performance Application Programming Interface (PAPI) is a portable interface (in the form of a library) to hardware performance counters on modern microprocessors. It is being widely used to collect low level performance metrics (e.g. instruction counts, clock cycles , cache misses ) of computer systems running UNIX / Linux ...
Netdata is designed to be installed on a system without interrupting any of the applications running on it. It operates according to the memory requirements specified by the user, using only idle CPU cycles.
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.
