Interactive monitor that displays CPU, memory, network, and disk usage. mpstat -P ALL 5 #10 Using nmon-Overall System Monitoring Run mpstat followed by a time interval (e.g., mpstat 5) to analyze CPU usage for each processor. du -sh /path/to/directory #9 Using mpstat for Multi-Processor Usage Use du followed by a directory path, and add -h for human-readable output, to assess the space used by that directory and its sub-directories. df -h #8 Using du for Directory Space Usage Type df in the terminal, and use the -h flag for a human-readable format, to examine disk space usage for each mounted filesystem. netstat -a #7 Using df for Disk Space Usage free -h #6 Using netstat for Network StatisticsĮnter netstat to view network connections and routing tables, and add flags like -a or -t for more detailed information. Run the command free, and use -m or -g for outputs in MB or GB, respectively, to review your system’s memory usage. iostat 5 #5 Using free to Check Memory Usage Install the sysstat package with sudo apt-get install sysstat, use iostat along with an optional time interval to observe CPU statistics and I/O transfer rates.

For example: vmstat 5 #4 Using iostat for CPU and I/O Statistics #3 Using vmstat for Virtual Memory StatsĮxecute ‘vmstat’ followed by a time interval to monitor virtual memory statistics, including swap usage and system operations. Then run it by typing “ htop” in your terminal to see a user-friendly display of processes. To use the htop command, first install it using the command below: sudo apt-get install htop top #2 Using htop for Enhanced Monitoring

Open a terminal and enter the command below to view real-time system resource usage, including CPU, memory, and process information. Here’s a guide in sentence form for each tool: #1 Using top for Real-Time Monitoring Monitoring system resources in Linux using command line tools involves several steps with various commands. Process to Monitor System Resources in Linux with Command Line Tools Now that we’ve established the importance of this skill, let’s move to the next section where we will explore how to monitor system resources in Linux using command-line tool. Monitoring tools can also help in identifying unusual activities that might indicate a security breach, such as unexpected spikes in network traffic or unusual processes consuming resources. You can predict when you’ll need to upgrade hardware or scale your system based on trends in resource usage. Regular monitoring provides data over time, which can be crucial for capacity planning. For instance, if a server is responding slowly, monitoring tools can help determine if it’s due to high CPU load, insufficient memory, or other resource constraints. Understanding resource usage helps in diagnosing and resolving system issues. This allows you to make adjustments to optimize the performance of your system or applications. By monitoring system resources, you can identify processes or applications that are consuming excessive resources, such as CPU, memory, or disk I/O. Here are five key reasons why this skill is important: Knowing how to monitor system resources in Linux is crucial for several reasons, particularly for system administrators, developers, and power users. What Makes Monitoring System Resources in Linux Essential Follow along and discover the power of command line tools for monitoring system resources in Linux. You’ll learn how to track and manage your Linux system’s resources precisely and efficiently. Whether you’re a system administrator or a curious user, this guide introduces you to the essential command line utilities that give you real-time insights into your system’s CPU usage, memory allocation, and more. Learn how to monitor your Linux system’s performance using command line tools with our easy-to-understand guide.
