Top 8 Linux System Monitoring Tools You Should Try

Linux offers many graphical, web‑based, and command‑line utilities for monitoring system performance, similar to Windows Task Manager. The following tools provide real‑time insight into CPU load, memory usage, network traffic, and hardware details, enabling users to diagnose bottlenecks and maintain system health.

1. Stacer

Stacer is a powerful system optimizer and application monitor that presents CPU, memory, and disk usage, lets users manage startup applications, and control services.

System overview : detailed CPU, memory, and disk statistics.

Startup application management : enable or disable programs that run at boot.

Service control : start or stop unnecessary services to improve performance.

2. htop

htop is an interactive process viewer that displays system processes and resource usage with color‑coded metrics, sortable columns, and a user‑friendly interface for killing or renicing processes.

Color‑coded resource usage : quickly spot high‑consumption processes.

Sorting : order processes by CPU, memory, etc.

Friendly UI : manage processes directly from the terminal.
