iostat -x: Show more details statistics information.The flag “-t” will define how many times each report should be displayed. Use the flag “-x” for extended statistics. To check only CPU statistic, use following command: It’s available on almost any Linux distro. The iostat tool comes as a part of the sysstat package. Unlike top or htop, iostat doesn’t offer real-time system monitoring. It monitors system input/output by observing the time the devices are active in relation to their average transfer rates.

The iostat command in Linux is used for monitoring system input/output statistics for devices and partitions. It also offers both horizontal and vertical scrolling. The texts are colorized and pleasant to look at. The default display of the htop is more comfortable to work with. htop is a newer program compared to top command, and it offers many improvements over top command. Htop command allows the user to interactively monitor the system’s vital resources or server’s processes in real time.

S: Sort the list by how long processes have been running.I: Remove idle processes from the list.It also offers interactive options to modify its behavior and perform various actions. In the first section few lines give a summary of the system resources with CPU utilization and second section display list of processes and threads currently being managed by the Linux kernel. The output of the top command divided into two sections. Some of the tools come pre-installed with all Linux distros, some may require manual installation. Linux has various built-in system calls to extract performance readings.

Following commands can work on any Linux machine. To ensure the most out of the limited processing power, it’s necessary to monitor how this resource is used.įor this demonstration purpose, we’re using Ubuntu 20.04 server. The performance of the CPU is one of the major determinants of the performance of a system. In this article, we’ll explain 3 ways to check CPU utilization in Linux.ĬPU utilization refers to a usage of processing resources, or the amount of work handled by a CPU.
