Of course - however, precisely how you do it depends on the server.

Have a look at the plugin writers guidelines in the docs.

Then, write some code to

. have your 'SQL server' client - if you don't have the client code on
the Nag host see below - to make the query

. compare the result of the query to the threshold and

. set the return code and write some output (for the human reading the
alert) accordingly.

Alternatively, if the 'SQL server' client code is _not_ on the Nag host,
then run it on the host it is installed on with something like NRPE or
use NCSA to submit its result to the Nag host.

If this is procedure is runnable from the shell (at a CLI), you can
wrap it in the trivial extra bits required by Nag and use it as a
a plugin.

Or, use Tom De Blendes canonical answer to this question,

HTH,

Yours sincerely.
