prettysmart

Overview

prettysmart is a command-line tool for monitoring and analyzing SMART (Self-Monitoring, Analysis, and Reporting Technology) data from storage devices. It provides detailed information about the health status of NVMe and SATA drives in an easy-to-read format.

Features

• NVMe Support: Comprehensive monitoring of NVMe SSDs including:

  • Drive health percentage
  • Available spare blocks
  • Temperature monitoring
  • Power-on hours and cycles
  • Data units read/written
  • Media errors and error log entries
  • Thermal throttling events
  • PCIe interface information (generation and lane width)

• SATA Support: Monitoring of SATA drives including:

  • Reallocated sectors
  • Pending sectors
  • Offline uncorrectable sectors
  • UDMA CRC errors
  • Spin retry count
  • Drive health remaining
  • SSD life remaining (for SSDs)
  • Reserved capacity available
  • Media wearout indicator
  • Wear leveling count
  • Total data read/written

• Multi-language Support: German and English interfaces

• Color-coded Output: Easy-to-read status indicators with color coding for critical, warning, and normal states

• Tabular Format: Well-organized table display of SMART attributes

Installation

Prerequisites

• Rust toolchain (rustc, cargo)
• smartctl from smartmontools package

Building from Source

Clone the repository and build:

git clone https://github.com/DocBrown101/prettysmart.git
cd prettysmart
cargo build --release

The binary will be created at target/release/prettysmart.

Usage

Simply run the tool (requires root privileges):

sudo ./target/release/prettysmart

Or install it to your PATH:

sudo cp target/release/prettysmart /usr/local/bin/
sudo prettysmart

Language Selection

The tool automatically detects the system language based on LANG or LC_ALL environment variables. To force a specific language:

For German:

sudo LANG=de_DE.UTF-8 ./target/release/prettysmart

For English:

sudo LANG=en_US.UTF-8 ./target/release/prettysmart

Output Example

The tool displays a table with SMART attributes for each detected storage device, including:

• Device model and interface type
• Current health status
• Warning indicators (if any)
• Detailed metrics in a tabular format
