Atop FOR LINUX

Experience a powerful process viewer, system monitoring, and task manager software with Atop FOR LINUX. This open-source project offers users a sophisticated and interactive tool that runs seamlessly from the Linux console or any X11 terminal emulator application.

Key Features:

• Highlight critical resources


• View only activities or deviations


• Permanent logging of resource utilization


• Scalable window width


• Accumulated process activity per user or program


• View network activity per process

Main Characteristics:

Atop utilizes all relevant resources of a Linux system, including CPU, RAM, SWAP, network utilization, and disk I/O. It displays resource utilization by all processes active at a certain moment.

The application has been designed to be a drop-in replacement for the traditional Top process viewer program in Linux-based operating systems.

Its Ncurses-based ASCII user interface comprises two main view areas of almost the same size, unlike traditional top programs like Unix Top or Htop. Both areas are updated regularly in real-time.

System Monitoring:

Atop displays detailed information about system-level activity, including CPU utilization, system memory, Swap partition, disks, and network interfaces.

Task Management:

The application shows the current running processes using the CPU of the machine. It sorts them based on various parameters like PID, Real User ID (RUID), Effective User ID (EUID), threads, CPU utilization, memory growth, disk activity, and more.

While Atop offers a decent process viewing experience, many users prefer using Htop or Top programs for their daily system monitoring tasks.
