Considering the time and risk of using off the shelf applications like
Nagios, I think rolling your own is a viable approach.

Other than Erlang itself, I don't know of a well designed, very light
Erlang monitoring framework. Probably because it's easy enough to
build something tailored to your needs directly in Erlang.

I'd just start doing what you're describing. I suspect that you'll
have a workable framework for monitoring in a few iterations.
