🖥️ Mini Monitoring App

A sample project designed for learning SRE and DevOps skills.
This repository contains a small Go service that exposes simple metrics (health check & latency), then gets monitored using Prometheus and visualized with Grafana.
The project demonstrates how to containerize applications.

🎯 Project Goals

• Build a lightweight service in Go
• Dockerize the application for portability
• Collect metrics with Prometheus
• Visualize metrics on Grafana dashboards
• Prepare infrastructure for CI/CD pipelines (GitHub Actions / GitLab CI)

🛠️ Tech Stack

• Golang → core service
• Docker → build & run container images
• Prometheus → monitoring & metrics collection
• Grafana → dashboards & visualization

🚀 Getting Started

1. Clone the repo

git clone https://github.com/NeginSal/Mini-Monitoring-App
cd mini-monitoring-app‍‍‍

‍‍‍‍ 2. Build the Docker image

‍‍‍‍docker build -t mini-monitoring-app .

3. Run the container

docker run -p 8080:8080 mini-monitoring-app

Now the service is available at: http://localhost:8080/health

🌐 Services

Go App → http://localhost:8080

Prometheus → http://localhost:9090

Grafana → http://localhost:3000 (default user/pass: admin / admin)

🐳 DockerHub Image

You can pull and run the app directly from DockerHub:

docker pull negin007/mini-monitoring-app:latest
docker run -p 8080:8080 negin007/mini-monitoring-app:latest

📊 Monitoring Setup

• Prometheus scrapes metrics from the Go application.
• Grafana provides dashboards and visualization.
