What is atop?
Atop is a full-screen ASCII performance monitor for Linux that reports system and process activity in real-time and logs data for long-term analysis. It tracks CPU, memory, disk, network, and process-level metrics—including finished processes—helping administrators identify resource bottlenecks and performance issues.
Linux system administrators, DevOps engineers, and performance analysts who need detailed, persistent monitoring of system resources and processes for troubleshooting and optimization.
Atop provides comprehensive, persistent monitoring with minimal overhead, capturing all process activity (even after exit) and offering both real-time views and historical logs, making it a robust alternative to basic tools like top or htop.
