A monitor question

I would think at a minimum you could tweak the Timeout and Time Until Up values in a standard monitor. Timeout would be some number greater than the interval such that the interval would pass 3 times before marking the node down. Time Until Up would be some number greater than the interval such that the interval would pass 2 times before the node was marked up. The timing of course relies on your application, but I think you can get pretty close to what you're asking for.

 

 

Otherwise, if you absolutely need a hard number of attempts (versus time), then a scripted monitor may be your best bet.
