✨ Features

• Prometheus: Efficiently collects and stores system metrics.
• Node Exporter: Exposes detailed hardware and OS metrics from your host.
• Grafana: Creates stunning, customizable dashboards for data visualization.
• Persistent Storage: Safely stores Prometheus and Grafana data.
• Docker Compose: Enables quick setup with a single command.

---

📋 Prerequisites

Ensure the following are installed on your system:

• Docker (latest version recommended)
• Docker Compose (version 3.8 or higher)

---

🚀 Installation !

Follow these steps to deploy the monitoring stack:

1. Clone the Repository

git clone https://github.com/amintoorchi/Dockerized-Grafana-NodeExporter-Prometheus.git
cd Dockerized-Grafana-NodeExporter-Prometheus

2. Launch the Services

Start the containers in detached mode:

docker compose up -d

sudo chown -R 65534:65534 ./prom_data
sudo chmod -R 775 ./prom_data

3. Access the Services

• Prometheus: http://localhost:9090
• Grafana: http://localhost:3000
  Default credentials: admin / admin (update password after first login)

---

🛠️ Configuration

• Docker Compose: The docker-compose.yml is pre-configured. Customize ports or volumes as needed.
• Grafana Dashboards: Import pre-existing dashboards or create custom ones after logging in.
• Storage:
  • Prometheus data is stored in ./prom_data/.
  • Grafana configurations are saved in ./grafana-storage/.
  • Both directories are auto-created on first run and listed in .gitignore.

Note: Add ./prom_data and ./grafana-storage to .gitignore to prevent uploading sensitive data to GitHub.

Network Configuration

• Host Network Mode: Used by Node Exporter and Prometheus for direct access to host metrics.
• Portability: Switch to a bridge network in docker-compose.yml for cross-system compatibility.

---

Troubleshooting

Resolve issues with these steps:

• View Logs: Check container logs for errors:

  docker compose logs
  

• Port Conflicts: Ensure ports 9090 (Prometheus) and 3000 (Grafana) are available.
• Storage Permissions: Verify that ./prom_data and ./grafana-storage have proper permissions.
