hydromon

A lightweight system monitoring daemon written in Rust.

Features

• CPU: Usage, frequencies, and CPU states (user, system, idle, iowait, etc.)
• Memory: RAM and Swap usage
• Disk: I/O throughput/latency and storage space
• Network: Traiffic and connection states
• System: Load average, uptime, temperatures, and interrupts
• GPU: NVIDIA GPU metrics (fan speed, temp, power, VRAM) via NVML

Quick Start

1. Build and run

   cargo build --release
   ./target/release/hydromon

2. Configuration On the first run, it will automatically generate a hydromon.toml config file by detecting your current hardware (disks, network interfaces, temp sensors, etc.). You can edit this file to enable or disable specific metrics. (Check out hydromon.toml.template for an example).

3. Data Metrics are stored in hydromon.db (SQLite) in the same directory. You can easily query the data:

   sqlite3 hydromon.db "SELECT * FROM sys_summary ORDER BY timestamp DESC LIMIT 5;"
