Implement retrieval of SMART data for Ubuntu

[jamesmarkchan]

Research Linux API/Tools for SMART:

smartctl (from smartmontools): This is the standard and most common tool on Linux for accessing SMART data. It's usually pre-installed or easily installable via package managers.

/dev/sdX devices: Direct device interaction can be done, but smartctl abstracts this nicely.

Choose a Method and Implement:

Recommendation: smartctl via subprocess is the clear winner for Linux.

Parsing Output: Parse the smartctl output.

Populate Benchmark Object: Map the retrieved SMART values to the Benchmark object.

Objectives

• implement core features
  • Total Bytes Written
  • Power-On Hours
  • Drive Temperature
  • Remaining Life Percentage
• implement vendor dependent data
  • Wear Leveling Count
  • Bad Block Count
  • Program Fail Count / Erase Fail Count:
  • ECC Error Rate / Un correctable Soft Read Error Rate (raw read error rate)
• error log solution - cdm or comparable solution
• persists smart record through derby
• SMART Reports table for viewing saved and loading past SMART reports
• button (intuitive maybe green button) to trigger smart query - vs current tabbed solution
• GUI looks professional and intuitive layout

ProcessBuilder pb = new ProcessBuilder("pkexec", "/path/to/your/bundled/smartctl", "--json", "-a", "/dev/sda");
Process process = pb.start();
