SolarWinds Orion platform monitoring a complex hybrid OT/IT infrastructure with 600+ servers, 30,000 switch ports, and 100+ VoIP devices across Cisco, Fortinet, and Dell F5 network devices. The architecture centralizes network performance monitoring (NPM), configuration management (NCM), IP address management (IPAM), and application performance monitoring (SAM) through a main polling engine backed by SQL Server and distributed additional polling engines. Specialized modules including SEM for security events, SPM for patch management, and WHD for IT service desk provide comprehensive visibility across storage systems (Dell PowerScale NAS), virtual infrastructure (VMware vSphere with 40 ESX hosts and Nutanix), and operational technology applications (MES, SCADA, IIoT, AMR, ASRS). This enterprise-scale deployment demonstrates best practices for monitoring mission-critical OT environments while maintaining IT operational visibility through role-based access control and centralized alerting. Fork this diagram on Diagrams.so to customize module configurations, add additional polling engines, or adapt the architecture for your specific network topology and monitoring requirements.
