Nagios and ubuntu 16.04 run query on MSSQL - sql-server

Question

I am trying to build a set of tests in a nagios install I have on ubuntu 16.04, that are based on the results of queries run against a MSSQL server else where on the network, at this time I struggling plugin that still has support.
Any suggestions of ways to do this would be appreciated

This plugin will do exactly what you want.
Download it and place the script in your plugin directory (usually /usr/local/nagios/libexec)
Make sure you have the proper dependencies installed. Ubuntu 16.04 should be:
sudo apt-get install php5-sybase freetds-common libsybdb5
And then set up your command definition:
define command{
command_name check_mssql_query
command_line $USER1$/check_mssql -H $HOSTADDRESS$ $ARG1$
}
Then add it as a service to whatever Host monitors the MSSQL server:
define service{
host_name mssql-server
service_description MSSQL Query 1
use local-service
check_command check_mssql_query!--username USERNAME --password PASSWORD --port PORT --instance INSTANCE --database DATABASE --query QUERY
register 1
}
I suggest reading through the help of the plugin itself with the command:
./check_mssql -h
It has a lot more helpful information. Good luck!
