# Introduction/Description
# =========================
This is a plugin to monitor the values of SMART (Self-Monitoring, Analysis and Reporting Technology) attributes of hard and solid state drives, using smartmontool's smartctl in the background. ATA, SCSI and NVMe drives are supported. The plugin is a fork of check_smart released in 2009 by Kurt Yoder. Since then the plugin has undergone a lot of changes. It allows to monitor drives behind hardware controllers and added a lot of parameters to fine tune the checks and set thresholds (on a per attribute setting).
