Overview

This project is designed to provide a set of ready-to-use Docker Compose configurations for the following services:

• Glances: A cross-platform monitoring tool that provides a comprehensive overview of system resources.
• Grafana: A open-source analytics and monitoring platform used for visualizing time series data from various sources.
• Heimdall: A dashboard for organizing and accessing web applications and services.
• Node Exporter: A Prometheus exporter that collects hardware and OS metrics.
• Prometheus: An open-source systems monitoring and alerting toolkit used for recording real-time metrics in a time series database.

The configurations are set up with Docker Compose to allow easy setup and management of these services using Docker containers.

Prerequisites

To use these Docker Compose configurations, you need to have the following tools installed:

• Docker – A platform for developing, shipping, and running applications in containers.
• Docker Compose – A tool for defining and running multi-container Docker applications.

Make sure both Docker and Docker Compose are installed and running on your machine before proceeding.
