2 * check_ide-smart v.1 - hacked version of ide-smart for Nagios
3 * Copyright (C) 2000 Robert Dale <rdale@digital-mission.com>
4 *
5 * Net Saint - http://www.nagios.org
6 *
7 * Notes:
8 * ide-smart has the same functionality as before. Some return
9 * values were changed, otherwise the --net-saint option was added.
10 *
11 * Run with: check_ide-smart --net-saint [-d] <DRIVE>
12 * Where DRIVE is an IDE drive, ie. /dev/hda, /dev/hdb, /dev/hdc
13 *
14 * - Returns 0 on no errors
15 * - Returns 1 on advisories
16 * - Returns 2 on prefailure
17 * - Returns -1 not too often
