bash script to monitor cpu and memory usage

Please note that you need to install a special package called sysstat to take advantage of following commands. Find Linux CPU utilization and usage using the mpstat and other tools Open the terminal app and type the following: The htop command is equivalent to the top command but allows you to scroll vertically, horizontally, and much more.

Hence, use the apk command on Alpine Linux, dnf command/ yum command on RHEL & co, apt command/ apt-get command on Debian, Ubuntu & co, zypper command on SUSE/OpenSUSE, pacman command on Arch Linux to install the htop.

Please note that you need to type q key to exit the top command display. In a true SMP environment (multiple CPUS), top will operate in number of CPUs.

The task’s share of the elapsed CPU time since the last screen update, expressed as a percentage of total CPU time. You can see Linux CPU utilization under CPU statistics. In addition, the top output contains information related to overall Linux server status, including Linux uptime, load average, process counts, CPU status, and utilization statistics for both memory and swap space Top command to check Linux CPU usage or utilizationįig.01: top command in action (click to enlarge) This command monitors CPU usage, utilization, Linux process statistics, and memory utilization. It can display system summary info and a list of tasks currently managed by the Linux kernel. The top command under Linux furnishes a dynamic real-time view of a running system. Using the old good top command to find out Linux CPU Utilization Determine which process is eating the CPU(s).

Find out your system’s average CPU utilization since the last system reboot.Display the utilization of each CPU individually (SMP cpu).
