Introduction
-------------------------
This is a plugin to monitor the values of SMART attributes of hard and solid state drives. 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).
This is a plugin to monitor the health and values of SMART attributes of hard (HDD), solid state (SSD) and NVMe drives. 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).
