hmon

About

hmon is a real-time system resource monitoring tool for Linux. It provides detailed insights into CPU, GPU, memory, disk, network, processes, Docker containers, ports, and systemd services.

Features

• CPU — usage, temperature, frequency, per-core cycle breakdown
• GPU — utilization, temperature, clock, power draw, VRAM (NVIDIA + AMD/Intel)
• Memory — usage, buffers, cache, slab, swap
• Disk — space usage, per-device I/O throughput
• Network — interface throughput, TCP connection states
• Processes — top processes sorted by CPU, memory, GPU, or PID
• Docker — container status, CPU/memory per container
• Ports — listening ports with bound process
• Services — systemd unit status
• History — activity graphs with braille-character rendering

Modes

hmon offers three viewing modes: Default (full dashboard), Zen Mode (consolidated single-screen view), and Pro Mode (dense two-column layout with kernel stats).

Tech Stack

Built with C++20, CMake, and ncurses. Uses /proc filesystem, nvidia-smi, and Docker Engine API for telemetry data.
