Prometheus Node.js Middleware

Menoetius is a Node.js middleware designed to automatically instrument web applications and expose Prometheus-compatible metrics. It enables developers to easily gather response duration metrics (summary and histogram types) and fundamental Node.js system metrics, all accessible via a configurable `/metrics` endpoint. The library supports integration with popular HTTP frameworks like `http`, `express`, `hapi`, and `restify`. However, the package is currently at a very early version (0.0.3), was likely published many years ago, and appears to be abandoned, with no discernible updates or active development. It relies on `prom-client` for metric collection, which has evolved significantly since Menoetius's last release. Due to its unmaintained status, it may lack compatibility with modern Node.js versions and up-to-date Prometheus client best practices, making it unsuitable for new projects.
