See the list of hard drives in your system.
Notice entries like /dev/sda, /dev/sdb etc. Ignore the partitions labelled /dev/sda1, /dev/sda2, etc.

# ls /dev/sd*


Check where the munin plugins are storted in your system. Depending on your distribution, the plugins might be found here:


On Gentoo, they are found here:

The following will monitor /dev/sda:

# ln -s /usr/share/munin/plugins/smart_ /etc/munin/plugins/smart_sda
// OR, depending on your distribution:
# ln -s /usr/libexec/munin/plugins/smart_ /etc/munin/plugins/smart_sda

Restart the munin-node:

# service munin-node restart

Check that the plugin is properly activated:
$ nc localhost 4949
# munin node at localhost
... smart_sda ...

In the commands above, use the appropriate host name, and make sure smart_sda and other drives you might have configured are properly listed in the list of plugins.
