# Script Name: smart-drive-exporter.sh

# Version: 1.0
|

# Description: Prometheus exporter for SMART drive health metrics.
|
||||
# Reads SMART attributes from SATA and NVMe drives using smartctl
|
||||
# and exports temperature, reallocated sectors, pending sectors,
|
||||
# uncorrectable errors, power-on hours, wear leveling, NVMe health,
|
||||
# and overall drive health status.
