^ Author | [[ michael.adelmann@gmail.com | mikadel ]] |
^ Compatibility | Xymon 4.3 |
^ Requirements | Linux, smartmontools |
^ Download | None |
^ Last Update | 2011-10-06 |

===== Description =====

In conjunction with the smartmontools package this script monitors the S.M.A.R.T. status of your hard drives on Linux. This also works if your hard drives are "hidden" behind a raid controller.

Note: This currently only works for the first hard drive.


{{:monitors:smart.png?400|}}
===== Installation =====
=== Client side ===

Create the following files in your xymon client directory:

monitoring script: <xymon-client-ext>/smart

monitoring config: <xymon-client-etc>/smart.conf

xymon monitor config: <xymon-client-etc>/clientlaunch.d/smart.cfg


Find your RAID crontroller at http://sourceforge.net/apps/trac/smartmontools/wiki/Supported_RAID-Controllers and change CONTROLLER@smart.conf accordingly.

Additionally you have to allow sudo for hobbit. Edit visudo and add this line:

hobbit  ALL=NOPASSWD:/usr/sbin/smartctl

=== Server side ===

None.
