Command to Check CPU Usage in Linux

In the world of Linux, monitoring system performance is crucial to ensure optimal resource utilization and troubleshoot potential issues. One of the essential tools for this purpose is pidstat, a command-line utility that measures the average CPU usage of Linux processes. In this article, we will explore how to use pidstat to check the CPU usage of individual processes or all available Linux processes.

To get started, you need to install the sysstat package on your Linux system. If it's not already installed, you can do so using the following commands:

* On Ubuntu, Debian, or Linux Mint: `sudo apt install sysstat`

* On CentOS, RHEL, or Fedora: `sudo yum install sysstat`

Alternatively, if the sysstat package is not available on your system, you can build it from source. This process involves downloading the source code and following the installation instructions.

Now that pidstat is installed, let's see how to use it to measure the average CPU utilization of a particular Linux process or all available processes.

Measuring Average CPU Utilization of a Particular Process

To measure the average CPU usage of a specific process, you can use the pidstat command followed by the process ID (PID) of the process. For example:

```

pidstat -p

```

Replace `` with the actual PID of the process for which you want to measure the CPU usage.

Measuring Average CPU Utilization of All Available Processes

To measure the average CPU usage of all available processes, simply run the pidstat command without any additional options:

```

pidstat

```

This will display a table showing the CPU usage statistics for each process on your system.

In conclusion, pidstat is a powerful tool for monitoring Linux process-level CPU usage. By installing and configuring sysstat, you can use pidstat to measure the average CPU utilization of individual processes or all available processes on your Linux system. This information can be invaluable in identifying performance bottlenecks and optimizing system resource utilization.
