# Introduction/Description
# =========================
The plugin check_smart by Kurt Yoder was imho the best plugin to monitor SMART status/values of hard drives. Unfortunately to my big surprise, the plugin was not able to handle other device types than ata or scsi. Therefore disks attached to hardware raids like megaraid could not be checked. I modified the plugin so it also works with disks attached to raid controllers.
Since October 2013 the plugin now also works on FreeBSD.


# Successful tests/examples
# =========================
SATA disk behind MDRaid (Software Raid) on Linux:
/usr/lib/nagios/plugins/check_smart.pl -d /dev/sda -i ata

MegaRAID on Linux:
/usr/lib/nagios/plugins/check_smart.pl -d /dev/sda -i megaraid,8

Intel RAID on FreeBSD 9.2 ("kldload mfip.ko" required):
/usr/local/libexec/nagios/check_smart.pl -d /dev/pass0 -i scsi

SATA drives behind Intel RAID on FreeBSD 9.2 ("kldload mfip.ko" required):
/usr/local/libexec/nagios/check_smart.pl -d /dev/pass12 -i sat

SCSI drives behind HP RAID (CCISS) on FreeBSD 6.0:
/usr/local/libexec/nagios/check_smart.pl -d /dev/ciss0 -i cciss,0
OK: no SMART errors detected|defect_list=0 sent_blocks=3093462752 temperature=24;;68

/usr/local/libexec/nagios/check_smart.pl -d /dev/ciss0 -i cciss,3
WARNING: 48 Elements in grown defect list | defect_list=48 sent_blocks=1137657348 temperature=22;;68

Using threshold option (-b) to ignore 1 bad element, warning only when 2 bad elements are found:
/usr/local/libexec/nagios/check_smart.pl -d /dev/ciss0 -i cciss,1 -b 2
OK: 1 Elements in grown defect list (but less than threshold 2)|defect_list=1;2;2;; sent_blocks=2769458900762624 temperature=27;;65
