# Multigraph plugin to monitor harddrive temperature, condition, 

# performance and estimated remaining lifetime through HDSentinel.

#

# To use, download the latest HDSentinel for Linux x86 or x64 from

# http://www.hdsentinel.com/hard_disk_sentinel_linux.php

# Unzip to /usr/local/bin/, make executable (chmod +x HDSentinel)

# in /etc/munin/plugin-conf.d/munin-node add the following lines

#

#  [hdsentinel]

#  user root

#  group root

#

# Copy this plugin to /usr/share/munin/plugins, and symlink it to

# /etc/munin/plugins, and then restart node.
