SolarWinds MSP centralized monitoring architecture connects multiple customer sites through VPN gateways and WAN transport to a central MSP data center running the Orion Platform. Customer firewalls, core switches, and servers at each site feed performance data via VPN concentrators to the MSP firewall, where SolarWinds Main Poller aggregates metrics from NPM, SAM, NCM, and Log Manager modules. The architecture enables MSP engineers to monitor network performance, server health, configuration compliance, and syslog events across all customer environments from a single Orion Web Console backed by SQL Server. This hub-and-spoke design reduces operational overhead, improves visibility across customer infrastructure, and simplifies troubleshooting for managed service providers.
