Prometheus & Node Exporter Installation Automation

This repository provides automation scripts to install and configure Prometheus and Node Exporter on Linux-based systems. The scripts handle system architecture detection, package installations, and the automatic setup of Prometheus and Node Exporter as systemd services.

Features:

• Prometheus installation: Installs the latest version of Prometheus, configures it, and sets up as a systemd service.
• Node Exporter installation: Installs the latest version of Node Exporter to monitor system metrics such as CPU, memory, and disk usage.
• Automatic package installation: Detects your system's package manager (APT, YUM, DNF) and installs the required dependencies.
• Service setup: Configures Prometheus and Node Exporter as services, ensuring they start on boot.
• Architecture detection: Supports both x86_64 and aarch64 architectures, ensuring compatibility across different hardware.
