CPU Utilization in Linux: Monitor and Optimize Your System Performance

System resource monitoring is an essential aspect of ensuring optimal system performance. In this article, we will explore three ways to check CPU utilization in Linux, which is crucial for maximizing the processing power of your server.

Overview of System Resources

Before diving into the details of CPU utilization, let's take a glance at the overall system resources. The first section of this output provides an overview of the system resources, including CPU utilization. This information is essential for identifying potential bottlenecks and optimizing system performance.

Processes and Threads Managed by Linux Kernel

The second section displays the list of processes and threads currently being managed by the Linux kernel. This information can be obtained using the top command, which is a powerful tool for monitoring system resources.

Built-in System Calls for Performance Readings

Linux provides various built-in system calls that allow you to extract performance readings from your system. These system calls can be used to monitor CPU utilization, memory usage, and other important system metrics.

Commands for Monitoring CPU Utilization

The following commands can work on any Linux machine, including Ubuntu 20.04 server:

1. top command: The top command provides a real-time view of the running processes and their corresponding resource utilization.

2. mpstat command: The mpstat command displays information about CPU usage and other performance metrics.

3. pidstat command: The pidstat command monitors the process and thread activity, providing detailed insights into CPU utilization.

Importance of Monitoring CPU Utilization

Monitoring CPU utilization is crucial for ensuring optimal system performance. The performance of a CPU directly affects the overall performance of your system. By monitoring CPU utilization, you can identify potential bottlenecks and take steps to optimize system performance.

In this article, we have explored three ways to check CPU utilization in Linux. Whether you're using Ubuntu 20.04 server or any other Linux distro, these commands can help you monitor and optimize your system's processing power. By following the tips outlined in this article, you can ensure that your system is running efficiently and effectively.
