# This plugin checks the temperature via hddtemp
|
|
#
|
|
# I wrote this check-Script, because all other tools didn't do what I wanted.
|
|
# The goal was:
|
|
# - hddtemp is to be used (small, fast)
|
|
# - a better output (with manufacturer and model)
|
|
# - deliver performance data
|
|
# - options in linux style
|
|
# - it should do its job perfectly
|
|
#
