In today's fast-paced digital world, monitoring the performance of your CPU is crucial to ensure optimal system performance and prevent any potential issues. This article aims to provide a comprehensive guide on CPU monitoring in the Linux environment. We will explore various tools, commands, and techniques that can be used to monitor CPU usage, temperature, and performance in a Linux system.

Examples:

1. Checking CPU Usage: To monitor CPU usage in Linux, the "top" command is widely used. Open a terminal and run the following command:

   top

   This command will display real-time information about CPU usage, including the percentage of CPU being used by each process, system load averages, and memory usage.

2. Monitoring CPU Temperature: To monitor CPU temperature in Linux, we can use the "lm-sensors" package. Install it using the following command:

   sudo apt-get install lm-sensors

   Once installed, run the following command to detect and display CPU temperature:

   sensors

   This command will provide temperature readings for various sensors, including the CPU.

3. Analyzing CPU Performance: To analyze CPU performance in Linux, the "perf" command-line tool is widely used. It provides a vast array of performance monitoring features. For example, to measure CPU cycles, run the following command:

   perf stat -e cycles <command>

   Replace "<command>" with the actual command you want to measure. This will provide detailed information about the number of CPU cycles executed by the command.
