Configured and deployed Paessler PRTG Network Monitor to simulate enterprise-grade monitoring for Microsoft 365 services and system health. The lab focused on real-time visibility and performance analysis across critical components. Key activities included: Sensor Configuration: Added sensors for Microsoft 365 services (Exchange Online, Teams, SharePoint, Defender XDR, Intune, etc.) and system health metrics (CPU load, memory, disk usage). Service Status Monitoring: Implemented dashboards to track uptime, downtime, and degraded states for Microsoft 365 workloads. Performance Analysis: Visualized live data and historical trends for system health, including CPU utilization and memory availability. Tools & Technologies: PRTG Network Monitor, Microsoft 365 Services, Network Performance Monitoring, Outcome: Successfully demonstrated proactive monitoring and incident management capabilities, ensuring visibility into service health and system performance for business continuity.
