SysInfo Health Checker (PowerShell & Bash)

📌 Project Overview

The SysInfo Health Checker is a lightweight, cross-platform endpoint diagnostic tool engineered for Help Desk and Systems Administration teams. It automates system diagnostic checks across Windows and Linux environments, printing hardware utilization, networking, disk capacity, and service health metrics directly to the console while writing persistent audit logs to disk.

🛠️ Features & Functionality

• Hardware Resource Monitoring: Calculates RAM utilization percentage and identifies CPU specs/load averages.
• Disk Capacity Alerting: Scans system drives and highlights volumes with under 15% free disk space.
• Network Adapter Querying: Retrieves active IPv4 configuration, subnets, and host network parameters.
• Service State Auditing: Monitors essential operating system services (e.g., Print Spooler, DNS Client, Windows Update, SSH, UFW Firewall).
• Automated Audit Logging: Appends clean, timestamped output logs to a persistent .txt audit file for record-keeping.
