Are you tired of your Linux system slowing down or crashing without warning? Do you want to keep a close eye on your CPU and memory usage to ensure your system is running smoothly? Look no further! In this blog post, we’ll show you how to easily monitor CPU and memory usage on Linux. Whether you’re a beginner or a seasoned pro, these tips will help optimize your system’s performance and prevent any unexpected hiccups along the way. So sit back, grab a cup of coffee, and let’s dive in!


There are a few different ways to monitor CPU and memory usage on Linux, each with its own set of pros and cons. This guide will detail the three most popular methods: top, htop, and free.

top is by far the most popular tool for monitoring CPU and memory usage on Linux. It provides a simple interface that displays a list of all running processes along with their current CPU and memory usage. The main downside of top is that it’s relatively slow compared to the other two options. htop is similar to top in that it displays a list of all running processes, but htop also includes information about active threads, processor cores, I/O wait times, and more. free is a powerful tool that can be used to find out how much memory (and disk space) is currently being used by various programs. It also has features for measuring system load and performance metrics. Overall, all three tools are useful for monitoring CPU and memory usage on Linux systems.


There are many ways to monitor CPU and memory on Linux.

One way is to use the top command. To use top, first type top at the command line. You should see a list of processes running on your computer. You can use the up or down arrow keys to move through the list and press the spacebar to select a process.

To view information about a process, you can use the following keys:

-R (for resources) shows the amount of CPU time, system memory, disk space used by that process, and number of active user sessions for that process.

-S (for status) shows the name of the program, its PID (process identification number), its percentage of processor usage, its load average (the average amount of work done by this process in recent minutes), and its signal count (how many signals it has received).

You can also use top to view memory information by using either -M or -D . The -M option displays all mounts in which a process has access, including those mount points in shared directories. The -D option displays only buffers used by a process. Buffer information is updated every second.


Linux has a number of commands that can be used to monitor CPU and memory usage. To list all of the available CPU and memory monitoring tools on Linux, type the following command:

$ cat /proc/cpuinfo | grep “^processor” | grep “^memory”

To view specific information about your CPU and memory usage, you can use one of the following commands:

$ cpuinfo | grep ‘model name’ $ free -m | grep “used_memory” $ top -b | grep “CPU utilization”


Linux has a number of tools and utilities that can be used to monitor CPU and memory usage. Some simple tools include the top command, which shows the currently active processes, and the htop utility, which provides a summary of all currently running processes. More comprehensive monitoring tools include the top-cpu tool and the vmstat tool. The former displays real-time CPU utilization, while the latter provides detailed information on CPU, memory, I/O, and network usage. Other useful utilities include ps aux and netstat -a, both of which provide information on running processes.

The most important step in monitoring CPU and memory usage is ensuring that you have accurate information to start with. To get accurate information using Linux, you’ll need to use a monitoring tool that provides accurate data collection at a granular level. For example, top gathers data at a process level while htop gathers data at a system level. If your system is resource constrained or you just want an overview of overall system performance instead of specific process details, either tool will work fine. However, if you’re looking for more detailed or specific information about individual processes or systems on your computer, then you’ll need to use one of the more specialized monitoring tools mentioned earlier.


There are a variety of ways to monitor CPU and memory usage on Linux. One popular method is the top command. This command prints a list of the processes that use the most CPU or memory. You can also use the ps command to get more specific information about individual processes. For example, you can use ps to see which processes are using the most memory.


In this tutorial, we will show you how to monitor CPU and memory on Linux.

To get started, open a terminal and type the following command:

sysctl -n hw.cpu_time_in_state
This will display the amount of time the CPU has spent in each state.
Next, use the following command to view the amount of memory in use:

free -m

You can also use the top command to see how much CPU and memory is being used by different processes:

top -c cpu -m


Monitoring CPU and Memory on Linux can be a challenge, but there are a number of tools that make the process easier. One popular tool is monit, which is available as part of the open sourceutils package.


There are a number of ways to monitor CPU and memory on Linux. Some popular utilities include top, htop, and free.

To view the status of all CPUs on your system, use the top utility. To view the status of individual cores, use the htop utility. To view the status of memory usage, use the free utility.

To determine which processes are using the most CPU time and memory, use the ps command. Use the -o option to display objects other than processes, such as threads or files. For example: ps -o %cpu %mem . This will output information about each process in terms of CPU usage (percentage) and memory usage (in bytes).


There are many ways to monitor CPU and memory on Linux. Here are five of the most popular.

1. top

top is a versatile command-line utility that displays information about the currently running processes and system resources on your machine. You can display CPU, memory, process information, and network traffic in real time or over a period of time.

2. ps

ps is another popular command-line utility for monitoring system resources on Linux. It lets you view the status of all currently running processes as well as detailed information about each one, such as its PID and user ID. You can also use ps to find out which processes are using up valuable system resources (such as CPU or memory), and how long they’ve been running for.

3. vmstat

vmstat is a tool that reports various statistics about the Virtual Machine (VM) subsystem on your machine. It includes information about the number of active VMs, their status (running or stopped), total memory size, number of CPUs, and more. vmstat can be very useful when trying to troubleshoot issues related to VMs or performance issues on your machine.

4. iostat

iostat is another classic tool for monitoring system performance in Linux Mint and other Ubuntu-based distributions. It reports information about the number of reads/writes performed by different kernel drivers, the amount of I/O wait time during disk operations,


With the proliferation of Linux-based systems, monitoring CPU and memory usage has become increasingly important. This guide will help you get started with monitoring CPU and memory on a Linux system.

There are many ways to monitor CPU and memory on a Linux system, but the most popular methods are using top and htop . Both tools provide basic information about the CPU and memory usage on a system, but they don’t offer all the features that you might want. For example, top doesn’t show you how much of each type of memory (RAM or swap) is in use, while htop can show you how much CPU time is spent in each process.

To get more detailed information about what’s happening on your system, you can use the perf command. perf is useful for tracking down performance issues in your application or kernel code. perf reports data in a format that’s easy to understand, so it can be a great tool for debugging problems.

If you’re looking to monitor specific processes or applications on your system, there are also several third-party tools that you can use. For example, AppArmor provides per-application protection policies that can be used to restrict which processes have access to which resources. The apparmor-profiles package contains profiles for popular applications like Firefox and Thunderbird, so you can easily restrict their access to hardware devices and file systems.
