I wrote something out of our need for better monitoring/metrics for Nginx here: https://luameter.com/ And quite a few people are using it for per-vhost metrics use case just like you said. Also if you prefer something simpler and open source I also wrote this https://github.com/lebinh/ngxtop

Second project is a hack that's reading log scripts.

That's not comparable to a proper monitoring page and exposing its stats by statsd (or similar) for integration with a real monitoring system.

nginx free edition is a black box, hence the criticism.
