Plugin for MSSQL Cluster via ODBC?

Hi all,
I need a plugin to connect to a mssql cluster via ODBC and check, if everything is fine. ODBC itself is up and running on my satellites.
First thought was to use check_mssql_health. Is it possible to run this with ODBC?
There is no static port for the instance. Only dynamic ports, which seems to be the problem right now.
Instances wth static (default) port 1434 can be monitoried withpout problems with check_mssql_health.
