I think OpenNMS has a way to set up a custom poller that can do
anything you want (e.g., connect to the database, issue a query,
check the results). I was playing with that a year or two ago; at
that time the OpenNMS documentation was pretty scant but I remember
coming across the feature in the release notes or some other document.
Monitoring the database with such a poller would tell you more about
whether the service is available than a simple TCP connect does.
