NetTCP health monitor

NetTCP is a custom microsoft protocol. You may be able to set up an external command, and write something to do this, but last time I reviewed the spec, there are a multitude of possible configuration scenarios (SSL encryption, binary packing, etc...). IIRC it also takes a couple of messages exchanged before you actually make your service call to test the endpoint. It may be easier to write something in C on a windows machine (or another linux box with Mono that shows the current state, and test that via an HTTP monitor). A HTTP to netTCP gateway if you will.

We usually pair this with an HTTP(s) endpoint to the same service, and just run two monitors; a TCP monitor for the 808 NetTCP port, and a HTTP monitor to the actual service application.
