+
+The goal of this project is to implement a comprehensive monitoring system for your server infrastructure using Prometheus for metric collection and Grafana for visualization. This setup will provide real-time insights into your server's performance, resource utilization, and overall health.
+
+## Requirements
+
+To begin this project, you'll need:
+
+- A running server to monitor. You can use an existing server from a previous project or setup a new server on [Digital Ocean](https://m.do.co/c/b29aa8845df8) or another cloud provider
+- An application running on the server using some dependencies e.g., Nginx, Node.js, or others.
+
+Once your server is operational, you'll proceed with setting up Prometheus and Grafana.
+
+### Prometheus Setup
+
+Prometheus is a powerful, open-source monitoring and alerting toolkit. Follow these steps to set it up:
+
+- Install Prometheus on your server
+- Configure prometheus for scarping intervals, endpoints and retention policies
+- Install and configure exporters for System metrics (CPU, memory, disk, network). Also setup additional exporters for services like Nginx, MySQL, MongoDB, etc.
+- Implement custom exporters or instrumentation for application-specific metrics
+
+Prometheus offers extensive data collection capabilities and a flexible query language (PromQL) for data analysis.
+
+### Grafana Configuration
+
+Grafana provides customizable dashboards for your metrics. You can setup a dashboard for system metrics and another for application metrics. Follow these steps:
+
+- Install Grafana on your server
+- Connect Grafana to Prometheus as a data source
+- Create dashboards for various metrics:
+  - System overview (CPU, memory, disk, network)
+  - Application-specific metrics
+  - Custom panels using PromQL queries
+- Set up user authentication and authorization for your Grafana instance
+
+### Advanced Goals
+
+For those looking to expand their skills and create a more robust monitoring system, consider implementing these advanced features:
+
+- Set up alerting rules in Prometheus and configure notification channels in Grafana (e.g., email, Slack)
+- Implement Prometheus recording rules to optimize query performance
+- Use Prometheus service discovery for automatic monitoring of dynamic environments
+- Integrate log aggregation using Loki and correlate logs with metrics in Grafana
+- Create a custom exporter for a specific application or service you're running

+This project will provide you with hands-on experience in setting up a production-grade monitoring system. You'll gain valuable skills in metric collection, data visualization, and system observability, which are crucial for maintaining reliable and performant infrastructure.
