In the world of Linux, having the ability to monitor your system’s performance is crucial. It gives you the power to effectively manage resources and troubleshoot any issues that may arise. There are numerous tools available for this purpose, each with its own set of features and benefits. In this article, we will take a closer look at ten of the most popular Linux CPU monitoring tools.
topis more than just a Linux monitoring tool, it’s an institution in itself. It provides a dynamic, real-time view of a running system.
topdisplays system summary information and a list of tasks currently being managed by the Linux kernel. The real-time, dynamic view of the processes in your system gives you a comprehensive understanding of how your resources are being allocated. To master the use of this powerful tool, you can refer to our step-by-step guide on mastering the ‘top’ command in Linux
htoptakes the concept of
topand enhances it, offering a full list of processes running, instead of the top resource-consuming ones. Its interactive, user-friendly interface uses color to provide visual information about processor, swap, and memory status. Plus,
htopgives you the power to interact with processes for better control.
- vmstat: With
vmstat(Virtual Memory Statistics), you get access to reports about processes, memory, paging, block IO, traps, and CPU activity.
vmstatcan help detect system bottlenecks by offering a summary view of the system’s performance, providing invaluable information for optimizing your system’s resources.
iostat(Input/Output Statistics) focuses on system input/output device loading, observing the time devices are active relative to their average transfer rates. It helps you monitor system performance and tune your system for optimal results.
mpstatis a specialist in reporting processor-related statistics. It can function both on multiple processors and to produce detailed reports about processor-related statistics, giving you granular control over your CPU usage.
sar(System Activity Reporter) is a multi-faceted tool that collects, reports, and saves system activity information. It generates a variety of performance metrics including CPU, memory, IO, load, and network data, providing a comprehensive overview of system health.
nmon(Nigel’s Monitor) is a versatile and comprehensive system monitoring tool. It provides data on CPU usage, memory, network, disks, file systems, NFS, top processes and more in a visually easy-to-read format or as a CSV file for later analysis, giving you the flexibility to analyze your system’s performance in various ways.
Glancesis a cross-platform system monitoring tool written in Python. It grabs system information from various libraries, can work in a client/server mode, and can export its data to text files, CSV, or even an InfluxDB database. This makes
Glancesnot only versatile but also adaptable to your specific requirements.
Netdataoffers real-time performance and health monitoring and displays the data in a user-friendly web interface. It is highly optimized to efficiently use CPU cores, memory and I/O, ensuring your monitoring activities do not disrupt the normal operation of your systems.
GKrellM(GNU Krell Monitors) is an attractive, feature-rich system monitoring tool. It monitors many aspects of your system, including CPU, memory, disk, and network usage. What sets
