PA Server Monitor can monitor servers within the local LAN with just the Central Monitoring Service. No additional software is needed.
If you want to monitor servers and devices that are on the other side of a firewall from the Central Monitoring Service (either within a corporate network, or across the Internet) then a Satellite Monitoring Service needs to be installed. The Satellite will do the monitoring at the remote location and report statistics and status information back to the Central Monitoring Service as shown in the image below.

NOTE: The Satellite Monitoring Service is only available in Ultra product editions.
