The repository contains a sample Node.js app that integrates the Prometheus client for node.js and exposes metrics on http:https://localhost:8080/metrics. The metrics are periodically scraped by Prometheus and visualized through a Grafana monitoring dashboard.

Make sure that you have Docker and Docker Compose installed:

• Docker Engine
• Docker Compose
