hdsentinel

Sadly there is no documentation for this plugin.

#!/bin/bash
# -*- sh -*-
#
# 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.
