Monitoring Server Report

Daily Server Monitoring to ensure readiness and prevent disruptions

Monitoring Server Report, a comprehensive and modular PowerShell framework developed to automate daily health checks across all domains managed by the System Administrators team.

Designed for scalability, extensibility, and legacy support, the solution accommodates a broad spectrum of Windows Server environments, from legacy platforms like Windows Server 2003 to modern deployments such as Windows Server 2022. Its modular design enables seamless integration across heterogeneous infrastructures, ensuring consistent and reliable monitoring regardless of server age, role, or domain membership.

 

The system leverages dynamic logic to adapt to remote execution constraints, legacy compatibility, and varying security policies, making it suitable for both cloud-connected and isolated environments.

Objectives:

  • Comprehensive Monitoring - Automate daily audits across key operational domains including memory, disk usage, CPU load, service status, certificate health, scheduled tasks, event logs, user access, antivirus status, time synchronization, and more.
  • Secure Execution - Utilize PowerShell remoting with configurable execution policies and fallback logic for legacy systems, ensuring safe and controlled data collection.
  • Structured Reporting - Generate timestamped HTML reports with optional visual charts, grouped by domain, server role, or health status, to enhance readability and facilitate decision-making.
  • Modular Architecture - Built as a collection of discrete, reusable functions, the system supports rapid extension to new audit categories or infrastructure changes without disrupting existing workflows.
  • Legacy Compatibility - Includes tailored logic for older systems, ensuring backward compatibility without sacrificing performance or reliability. Functions dynamically switch between WMI and CIM queries based on server capabilities.
  • Security & Compliance Visibility - Track local users, remote access permissions, antivirus health, firewall status, and audit policy configurations to support compliance and reduce risk exposure.
  • Operational Integrity - Monitor uptime, reboot history, pending restart flags, and backup job status to ensure systems remain stable, recoverable, and aligned with business continuity goals.

Core Components:

Server-main.ps1 - The main execution script. It reads the configuration, invokes the appropriate functions, aggregates results, and generates the final HTML report. This script coordinates the entire monitoring workflow.

  • Orchestrates the entire monitoring process
  • Loads configuration from Server-config.json
  • Invokes modular functions from Server-functions.ps1
  • Generates styled HTML reports using embedded logic and external CSS
  • Manages output directories and file naming conventions

Server-functions.ps1 - Contains all PowerShell functions responsible for executing system checks. Each function is modular, reusable, and designed to operate across different server versions.

  • Contains reusable PowerShell functions for each monitoring check
  • Implements logic for CPU, memory, disk, services, backups, antivirus, and more
  • Returns structured results for aggregation and reporting

Server-config.json - Defines the servers to monitor, services to check, and execution preferences. This file acts as the central configuration hub, allowing administrators to tailor the monitoring scope without modifying code.

  • Defines which checks are enabled or disabled
  • Defines which sections are collapsible
  • Lists target servers and critical services
  • Allows flexible customization without modifying script logic

HTML-style.css - Provides the visual styling for the HTML report. It ensures consistent formatting, color-coded status indicators, and responsive layout for easy viewing across devices.

  • Provides visual styling for the HTML report
  • Ensures readability, structure, and professional presentation
  • Applies consistent formatting to tables, headers, and status indicators
