Check MSSQL Server Centric Status

Can monitor many metrics. Developer is very open to critcism and fixing issues. Please contact me if you find something.

I also added a doc on the exchange, please refer to it if you're connecting to instances on an MSSQL database. It says Nagios XI on it but will still apply to Nagios Core as well:

https://assets.nagios.com/downloads/nagiosxi/docs/Nagios_XI_Installing_MSSQL_Wizard_Prereqs.pdf

Examples of use are:

./check_mssql_server.py -H 192.168.0.1 -U user -P password --lazywrites -w 20 -c 30

Now keep in mind if you're going to using percentages the w and c get a little trickier. This plugin is Nagios Plugin compliant as far as the bounding goes, fully supporting the use of the : ~ and @ symbols. Here is an example of what you'd do for the warns and crits on Buffer Hit Ratio:

./check_mssql_server.py -H 192.168.0.1 -U user -P password --bufferhitratio -w 95: -c 90:

This will return warning of the percentage goes below 95% and critical if it goes below 90%.

For information the the use of ~ : and @, refer to section 2.5 of the Nagios Plugin Guidline here: http://nagiosplug.sourceforge.net/developer-guidelines.html
