 # Metrics
 
-- This folder contains middleware that is used to intercept the requests for all the endpoints as well as the definition of the metrics that are collected.
+## Overview
 
-- Metrics server is started on port `8081` which collects the metrics from the monitor app and exposes them on the `/metrics` endpoint.
+The metrics system provides monitoring capabilities for the OpenZeppelin Monitor application through Prometheus and Grafana integration.
 
-- We use `prometheus` to collect metrics from the application. The list of metrics are exposed on the `/metrics` endpoint.
+## Architecture
 
-- To view prometheus metrics in a UI, you can use `http://localhost:9090` on your browser.
