# This script is designed to be used by Nagios. It checks for the availability of both Microsoft SQL Server 7 and 2000.
|
||
|
|
#
|
||
|
|
# Requirements:
|
||
|
|
#
|
||
|
|
# FreeTDS 6.0+ (http://www.freetds.org/)
|
||
|
|
#
|
||
|
|
# It was written by Tom De Blende (tom.deblende@village.uunet.be) in 2003.
|
||
|
|
#
|
||
|
|
# Version 1.0.
|
||
|
|
# Version 1.1: Rewritten the initial script so that it not only works from the CLI but also from within Nagios. Always helpful...
|
||
|
|
# Version 1.2: Grouped output so things look a bit better.
|
||
|
|
# Version 2.0: Rewritten the plugin to support version 6.0+ of FreeTDS.
|
||
|
|
# Removed sqsh requirement as version 6.0+ of FreeTDS now offers its own CLI client: tsql.
|
||
|
|
# Older versions of FreeTDS are no longer supported.
